▼ Software systems have become pervasive in everyday life and are the core component of many crucial activities. An inadequate level of reliability may determine the commercial failure of a software product. Still, despite the commitment and the rigorous verification processes employed by developers, software is deployed with faults. To increase the reliability of software systems, researchers have investigated the use of various form of redundancy. Informally, a software system is redundant when it performs the same functionality through the execution of different elements. Redundancy has been extensively exploited in many software engineering techniques, for example for fault-tolerance and reliability engineering, and in self-adaptive and self- healing programs. Despite the many uses, though, there is no formalization or study of software redundancy to support a proper and effective design of software. Our intuition is that a systematic and formal investigation of software redundancy will lead to more, and more effective uses of redundancy. This thesis develops this intuition and proposes a set of ways to characterize qualitatively as well as quantitatively redundancy. We first formalize the intuitive notion of redundancy whereby two code fragments are considered redundant when they perform the same functionality through different executions. On the basis of this abstract and general notion, we then develop a practical method to obtain a measure of software redundancy. We prove the effectiveness of our measure by showing that it distinguishes between shallow differences, where apparently different code fragments reduce to the same underlying code, and deep code differences, where the algorithmic nature of the computations differs. We also demonstrate that our measure is useful for developers, since it is a good predictor of the effectiveness of techniques that exploit redundancy. Besides formalizing the notion of redundancy, we investigate the pervasiveness of redundancy intrinsically found in modern software systems. Intrinsic redundancy is a form of redundancy that occurs as a by-product of modern design and development practices. We have observed that intrinsic redundancy is indeed present in software systems, and that it can be successfully exploited for good purposes. This thesis proposes a technique to automatically identify equivalent method sequences in software systems to help developers assess the presence of intrinsic redundancy. We demonstrate the effectiveness of the technique by showing that it identifies the majority of equivalent method sequences in a system with good precision and performance.

▼ This study aimed to examine the reasons why individuals in Aotearoa New Zealand tattoo their bodies and analyse the mechanism by which tattoo acts as a method of coping, self-healing and self-transformation for these individuals. Further this study aimed to investigate how tattoo allows individuals to re-write and transform their meaning of traumatic and/or stressful events into stories of empowerment, strength and survival. While tattoo has been explored for meaning and function in Aotearoa New Zealand, there was seen to be no empirically grounded research looking into how tattoo might serve as a therapeutic tool. The study examined 427 survey respondents and eight interviewees across Aotearoa New Zealand. The participants ranged in age from 18 to 65-years-old and varied across multiple ethnicities. This study combined quantitative and qualitative data collection methods in a two-phase project. Data collection phase one involved 427 participants respond to an online survey. This establised a baseline for cross-comparison of attitudes, backgrounds and life experiences. Data collection phase two involved eight semi-structured interviews to explore individual experiences and uncover the relationship between their tattoos and how it had helped them to cope/heal in some way. To analyse these interviews, thematic analysis was combined with phenomenological analysis. The findings from this study suggest that there are multiple reasons (expression of self, aesthetic aspects, identity, passage of rights, remembrance/tributes and personal healing among others) why individuals chose to engage in the art form of tattooing. Findings also suggest that tattoo, directly relating to the mind/body continuum of stress/trauma can serve as a mechanism to enable individuals to re-script stressful/traumatic events, reinforce identity and self-acceptance, acknowledge past difficulties and turn them into positives and increase inner motivations and positive thinking which was seen to initiate healing and recovery. This suggests that tattoo serves as a powerful mechanism to aid in personal transformation, but also challenge previous meanings associated with the art form of tattoo.

Damage in materials and structures is unavoidable, leading to the time deterioration of its functional properties (e.g. barrier, load bearing, aesthetics) and ultimate repair or replacement. Lifetime extension can be achieved by using materials with initially higher performance or using materials that can repair themselves (self-healing). The latter are materials capable of repairing themselves autonomously or with little human intervention, thereby partially or fully restoring their original material properties and performance. To be able to heal macroscopic damages a first key requirement is initial contact between broken faces. Only after this first step will the subsequent molecular processes be able to proceed with the healing at the molecular scale. In most studied concepts the contacting stage is performed by hand placing, limiting potential applications and highlighting the need for research to facilitate this necessary first step. This MSc research project addresses this problem by exploring the potential of magnetically induced damage closure. The main underlying idea states that magnetic forces at the crack plane should be sufficient to promote the bridging of broken parts, thereby facilitating the interfacial phenomena leading to healing. Such a concept can conceptually be implemented by using magnetic healable polymers, pending magnetic particles in the polymer or embedding particles as extrinsic phases. In a preliminary stage it was decided to study the latter experimentally as well as computationally. A hydrogel-composite consisting of poly(vinyl alcohol) polymer matrix mixed with iron-oxide (magnetic) particles was used as model system. Experiments showed that the presence or absence of a magnetic field does not affect the ultimate interfacial healing achieved. COMSOL simulations fed with experimental data showed the applicability of the concept in the presence of external magnetic fields for soft polymers and small gap distances. The results obtained demonstrate the viability of the concept to close damages as well as applying some interfacial pressure not affecting the ultimate healing levels.

▼ Shape memory polymers are smart materials capable of fixing a temporary shape and returning to their initial shape in response to an external stimulus. Since the discovery and acknowledgment of their importance in 1960s, shape memory polymers have been the subject of tremendous and continuous attention. In a previous study conducted on a biomimetic shape memory polymer (SMP), the ability of a self-healing composite to heal, and to repair and restore structural-length scale damage using a close-then-heal (CTH) self-healing mechanism was examined and validated. The present study is purposed with investigation of the effects on healing efficiencies of the variation of temperature during both thermo-mechanical programming and shape recovery under three-dimensional (3-D) confinement. The polymer considered was a polystyrene shape memory polymer with 6% by volume of thermoplastic particle additives (copolyester) dispersed in the matrix. After fabrication, and determination of their glass transition temperature using DSC, the specimens were allowed to go through a strain-controlled programming at a wide range of temperatures (20°C, 45°C, 60°C, 82°C, 100°C and 140°C), at a pre-strain level of 15%. Fracture was imposed using a three-point flexure apparatus, and was followed by shape recovery at multiple temperatures (73°C, 100°C, 122°C and 148°C). The self-healing efficiency was evaluated per flexural strength immediately after programming and following healing. The results and deductions attained were verified using EDS analysis and SEM inspection. It is inferred from the study that the programming temperature only very slightly affects the recovered strength. Programming the specimen above its glass transition temperature provided a marginal gain in strength recovery. Shape recovery (healing) temperature, however, was found to have a significant impact on the self-healing efficiency. A sudden “boost” was noted around the melting temperature of the thermoplastics, with a significant increase in the healing efficiency past the bonding temperature of the copolymer. It was observed that programming above the glass transition temperature of the composite and healing above the melting point of the thermoplastic addives ensured a maximum healing efficiency of up to 63% for the material considered.

▼ A capsule-based self-healing cementitious material, capable of autonomically repairing its own cracks, can extend the service life of concrete structures and decrease the costs associate with repair and maintenance actions. However, the size, shell thickness, shell material and mechanical properties of the capsules still need to be optimised to ensure self-healing performance. Thus, the objective of this research was to explore the controlled microfluidic encapsulation to investigate the production of microcapsules for physically triggered self-healing in cementitious materials. A flow-focusing microfluidic device was used to produce double emulsions to be selectively photopolymerised to generate a core-shell structure. Subsequently, the physical triggering was assessed by embedding the produced microcapsules in cement paste, fracturing it and observing the cracked surface in the SEM. The results showed the production of microcapsules with 80-140 μm of diameter with excellent control over size and shell thickness. Using water-in-oil-in-water (w/o/w) double emulsion, microcapsules were synthesised containing water, colloidal silica solution and sodium silicate solution as core material. In addition, an oil-in-oil-in-water (o/o/w) double emulsion was used to encapsulate mineral oil and emulsified healing agents. The formation of the core-shell structure with aqueous and organic cores was characterised using optical microscopy and SEM. It was demonstrated that the water is not retained inside of the capsule, resulting in the formation of dimples and buckled capsules, particularly for shells thickness ~7 μm. On the other hand, TGA confirmed the retention of mineral oil for shells thickness of ~2 μm and the encapsulation efficiency was demonstrated to be 66%. When the capsules were added to the cement paste, four key factors were observed to prevent physical triggering: (i) thick shells, (ii) buckling of thinner shells due to the loss of water core, (iii) mechanical properties and (iv) poor interfacial bonding. As a result, a mechanical characterisation of the shell material was performed, indicating brittle fracture at room temperature, reduced Young’s modulus when compared with cementitious matrix and stress at rupture of 15-36 MPa. In addition, an innovative methodology was proposed to functionalise the surface of the microcapsules with hydrophilic groups in order to increase the interfacial bonding between the cement paste and the microcapsules. Thus, microcapsules with low tensile strength, low shell thickness, organic core and good interfacial bonding were successfully synthesised and demonstrated to rupture upon crack formation. These results experimentally demonstrate the importance of reduced shell thickness, core retention and interfacial bonding as valuable guides during the design of microcapsules for physically triggered self-healing in cementitious materials.

▼ In the year 2006, Delft University of Technology started researching ‘Strain hardening Self-healing concrete’ (SSC). The reason for this research was the desire to increase the durability of concrete. This depends mostly on the reinforcement. To ensure a certain lifespan of concrete structures, a minimum cover depth has to be applied. However, cracks occur in the concrete and cause a significant decrease in durability. Research by M. Sierra-Beltran in 2014 resulted in SSC that has the capacity to seal these cracks due to the addition of a healing agent. Also, fibers are added to keep the cracks small and speed up the healing process. In this thesis SSC is compared with traditional concrete (TC). A structural design is made with both materials based on assumed characteristics. Also, tests are performed to check whether those assumptions are right and a short calculation with the results is made. When making a structural design with the assumed characteristics for TC and SSC, one finds that it is possible to design more slenderly with SSC than with TC. This is caused by the decrease in cover depth and the absence of extra reinforcement to control the crack width. The only exception is the height of the bridge deck; the height of the bridge deck is smaller in a TC design, caused by the low Young’s modulus of SSC. The positive effect of SSC is expected to be most noticeable on the bridge deck at the locations with negative bending moments. Other locations where the positive effects can be noticed are at the beams and the tensile bars. The material costs of the bridge designed with SSC are significantly higher than the material costs of the bridge designed with TC. However, it is expected that the maintenance costs of the SSC bridge are much lower. The results of the tests for the structural characteristics show that SSC mortar has a lower compressive strength and a lower Young’s modulus than TC mortar. Especially, the lower Young’s modulus affects the structural design. The flexural strength of SSC mortar is higher than the flexural strength of TC. The tests on durability give positive results. The chloride migration shows that, before healing, the SSC and TC have similar migration coefficients. However, after the healing period the migration coefficient of the SSC is lower than the migration coefficient of TC, at the location of the crack as well as the uncracked surface. Although, the difference is not as large as expected, this might change with longer healing periods. Therefore, it is recommended to do more tests with longer healing periods. When making a short calculation with the characteristics found in the results of the test, one sees that the height of the bridge deck and the beams increases a bit more than assumed due to the lower Young’s modulus. Furthermore, no large changes are found. Therefore, it is recommended to research the possibility of changing the mixture in a way that the Young’s modulus is increased.

▼ Damage in composite materials spans many length scales and is often difficult to detect or costly to repair. The incorporation of self-healing functionality in composite materials has the potential to greatly extend material lifetime and reliability. Although there has been remarkable progress in self-healing polymers over the the past decade, self-repair in fiber-reinforced composite materials presents significant technical challenges due to stringent manufacturing and performance requirements. For high performance, fiber-reinforced composites, the self-healing components need to survive high temperature processing, reside in matrix interstitial regions to retain a high fiber volume fraction, and have minimal impact on the mechanical properties of the host material. This dissertation explores several microencapsulated solvent-based self-healing approaches for fiber-reinforced composites at the fiber/ matrix interface size scale as well as matrix cracking. Systems are initially developed for room temperature cured epoxies/ glass fiber interfaces and successfully transitioned to carbon fibers and high temperature-cured, thermoplastic-toughened matrices. Full recovery of interfacial bond strength after complete fiber/matrix debonding is achieved with a microencapsulated solvent-based healing chemistry. The surface of a glass fiber is functionalized with microcapsules containing varying concentrations of reactive epoxy resin and ethyl phenyl acetate (EPA) solvent. Microbond specimens consisting of a single fiber and a microdroplet of epoxy are cured at 35C, tested, and the interfacial shear strengths (IFSS) during the initial (virgin) debonding and subsequent healing events are measured. Debonding of the fiber/matrix interface ruptures the capsules, releasing resin and solvent into the crack plane. The solvent swells the matrix, initiating transport of residual amine functionality for further curing with the epoxy resin delivered to the crack plane. Using a resin-solvent ratio of 3:97, a maximum of 100% IFSS recovery is achieved – a significant enhancement over prior work that reported 44% average recovery of IFSS with microencapsulated dicyclopentadiene (DCPD) monomer and Grubbs' 1st Generation catalyst healing agents. The effects of capsule coverage, resin-solvent ratio, and capsule size on recovery of IFSS are also determined, providing guidelines for integration of this healing system into high fiber volume fraction structural composites. High healing efficiencies are achieved with capsules as small as 0.6 µm average diameter. The resin-solvent healing system is then extended to repair of a carbon fiber/epoxy interfacial bond. A binder is necessary to improve the retention of capsules on the carbon fiber surface. Two different methods for applying a binder to a carbon fiber surface are investigated. Healing efficiency is assessed by recovery of IFSS of a single functionalized fiber embedded in an epoxy microbond specimen. The two binder protocols produce comparable results, both… Advisors/Committee Members: Sottos, Nancy R. (advisor), Sottos, Nancy R. (Committee Chair), White, Scott R.

▼ Engineering materials experience damage during their lifetime, which reduces their ability to carry load and maintain structural integrity. Self-healing materials have been developed to mitigate the effects of damage, however, there are currently limitations in the healable length scale of damage that can be addressed. Overcoming this challenge requires a shift from simply re-bonding of cracks, which describes many current self-healing systems. Features of biological regeneration can be used to inspire approaches to address larger length scales of damage and achieve repeatable replacement of damaged or lost material. This thesis focuses on development of strategies for synthetic regeneration in polymers. Concepts inspired by biological regeneration are applied to the problem of restoration of lost (damage) volume. Two specific damage modes that result in volumetric material loss are considered: impact puncture damage, and abrasive removal of a coating. This thesis focuses on demonstrating regeneration in response to these damage modes, and establishes experimental protocols for evaluation of performance. In addition, advancements are made in the fabrication of microvascular polymeric materials. The transverse impact of plates of vascularized transparent polymer results in a multiscale damage pattern in which a centimeter-scale central puncture of lost (damage) volume is opened up where the projectile is incident, as well as a network of radiating microcracks emanating from the impact point. An embedded microvascular network facilitates the delivery of a novel two-stage healing agent to the site of damage in order to restore the lost damage volume. The performance of the restored specimens is evaluated by both seal testing under pressurization and impact energy absorption under repeat impact testing. Factors affecting the impact restoration performance are explored. The formulation of the two-stage healing agents is modulated to improve impact energy absorption. Sealing of 100% of samples is achieved by a hybrid system incorporating both a vascular network and microcapsules to separately target large damage (central puncture) and small microcracks. Abrasive damage can result in complete removal of a protective coating and exposure of the underlying substrate. To regenerate the coating after damage, a single-part healing agent is released upon removal of the coating, and cures when exposed to simulated ambient sunlight. The regenerated coating is evaluated by hardness testing. Coating regeneration is facilitated by a pressurized microvascular system containing a compliant protective (UV blocking) valve. The polymeric coating is regenerated with the same hardness after large-scale removal, for four repetitive damage events (abrasion). To improve control of the volume of healing agent released in response to damage, an accumulator is developed for incorporation into microvascular coating systems. The accumulator enables the localized storage of a prescribed volume of healing agent. Upon damage, this stored volume… Advisors/Committee Members: White, Scott R (advisor), Sottos, Nancy R (Committee Chair), Freund, Jonathan B (committee member), Ewoldt, Randy H (committee member).

▼ The Autonomic Computing paradigm was first presented almost 18 years ago as a 20-30 year long research agenda. Organizations like NASA, have explored the possibilities of using autonomic systems in their future missions due to vast distances experienced in space exploration. Planetary and mobile robots operate in hostile environments and because of their remote location, human intervention for repairs is not possible. Hardware devices, like mobile robots, are susceptible to internal and external environmental changes, which can lead to faults occurring. Some research has been conducted in terms of handling faults in mobile robots but there is no generic autonomic model that can be used for any type of system fault, in any type of mobile robot. This Thesis describes a generic autonomic architecture for use in developing systems for managing hardware faults in mobile robots. Using autonomic principles, this Thesis focuses on how to detect faults within a mobile robot and how specialised algorithms can be deployed to compensate for the faults discovered. The initial design of a generic architecture is developed using inspiration from the MAPE-K and IMD architectures. Case studies are presented that show three different fault scenarios that can occur within the effectors, sensors and power units of a mobile robot. The results from each of the Case Studies is used to create and refine a generic autonomic architecture that can be utilized for any general mobile robot setup for fault handling. A further Case Study is presented, which exercises the generic autonomic architecture in order to demonstrate its utility. This Thesis addresses the fundamental challenges in operating remote mobile robots with little or no Human intervention. If a fault does occur within the mobile robot during field operations, then having a self-managing strategy as part of its processes may result in the mobile robot continuing to function at a productive level. Research in this Thesis has provided insights into the shortcomings of existing robot design which is also discussed.

▼ Spinel is one of the best known and widely used ceramic materials. It has good thermal shock resistance, high chemical inertness in both acidic and basic environments, excellent optical and dielectric properties, high strength at both elevated and normal temperatures, and has no phase transition up to the melting temperature (2135°C). Spinel is used in the metallurgical, electrochemical, and chemical industrial fields. It has also found some applications in dentistry, catalyst supports, humidity sensors, reinforcing fibers, photoluminescent materials, etc. One of the limitations of spinel ceramic is its brittleness. Furthermore, at high temperature applications, a rapid heating or cooling can cause a high thermal gradient. Building up of such thermal stresses can lead to surface microcracking and crack growth, which finally can lead to a catastrophic failure of the component. In order to overcome this problem, it is highly desirable that the self-healing capability of spinel and spinel composites are investigated. In this research for the first time we studied the crack self-healing capability of nanostructure spinel. The results showed that grain growth and sintering phenomena are the two factors controlling the healing procedures. In the case of spinel ceramic, cracks can be completely healed after annealing the specimens at 1600°C for 100h with the strength recovery of 91%. On the other hand, it has been found that SiC can be used as a healing agent in many ceramics even in those ceramics without any crack healing ability. Therefore, first SiC/spinel nanocomposite was synthesized using talc, aluminum and graphite powders. The sintering behavior of the SiC/spinel nanocomposite was investigated and the best pellets from physical and mechanical properties point of views were selected to study the self-healing behavior of SiC/spinel nanocomposite. The results showed that SiC/spinel nanocomposite has an exceptional crack-healing ability as the surface cracks can be healed after sintering the specimens at 1550°C for 1 min in air with the strength recovery of 99%. Reaction of SiC with air and formation of SiO2 and subsequently formation of mullite and dissociation of enstatite are the possible mechanisms responsible for crack healing in SiC/spinel nanocomposite.

▼ The boundary film formation and lubrication effects of low-molecular-weight silicone molecules with cationic side groups were studied. Poly-(N,N,N-trimethylamine-3-propylmethylsiloxane-co-dimethylsiloxane) iodide was synthesized and deposited on silicon oxide surfaces to form a bound-and-mobile lubricant film. The effects of the ionically bound layer and mobile multilayers were investigated. Both nano- and macro-scale tribological tests revealed superior lubrication performance of the silicon molecule with cationic side chains over the neutral silicon molecule (which was modeled with polydimethylsiloxane with the same molecule weight). The multilayer films exhibited characteristic topographic features due to ionic interactions within the polymeric film. In the macro-scale, the effects of ionic content, environmental condition, and advantage of the bound layer on self-healing will be discussed to demonstrate the wear resistance and self-healing capability. The multilayer spreading rates were estimated to be ~10^-11 m2/s. In the nano-scale, the results of disjoining pressure and viscosity measurements help understand the lateral spreading of the mobile layer and identify the mobile species. The mobile species are the reduced tertiary amine form of CPL. The hydrophobic but hygroscopic properties of CPL are also investigated with SFG and ATR-IR. The CPL-coated surfaces are hydrophobic which prevents the detrimental effects of humidity on wear of silicon. In addition, the hygroscopic nature of CPL allows humidity to be absorbed into the film, which enhances the self-healing capabilities. Finally, by texturing the silicon surface with nanowells, self-healing is enhanced when the nanowells are filled with CPL. The nanowells serve as CPL reservoirs that are readily available for self-healing within the wear track for faster cycle intervals. However, the nanowells deteriorate the self-healing from surrounding the contact region due to the refilling of the empty nanowells.

▼ Ruth Violet Bingham, PhD Thesis, The University of Manchester. Corrosion Protection and Self-healing in Nanocomposite Coatings. 2011Abstract:Recent interest in environmentally friendly alternatives to chromate-based corrosion inhibitors has led to the development of a range of novel coating formulations. The work described in this thesis has been aimed at investigating the mechanism of self-healing and active corrosion protection of the new coatings by searching for active components that have migrated from the coating to a controlled defect. The use of glow discharge optical emission spectroscopy (GDOES) has been investigated as a tool for both the generation of a reproducible controlled defect and for elemental depth profiling of the coatings and corroded substrates. Conclusions drawn from the elemental depth profiles have been validated by a range of characterisation techniques including optical microscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy (EDX) and electrochemical techniques.The work has focused particularly on a comparison of hybrid coatings doped with inhibitors encapsulated in nano-containers, as compared with the direct addition of inhibitor species to the coating matrix. The work also investigates the effects of inhibitor addition to sol-gel coatings or primer systems or both, highlighting possible synergistic effects of mixed inhibitor systems (for example, sol-gel coating doped with strontium aluminium polyphosphate (SAPP) supporting primers doped with benzotriazol (BZT) or mercaptobenzothiazol (MBT).The various coatings have also been studied in the absence of inhibitor species to assess the effectiveness of the coatings as barriers between the substrate and the corrosive environment. This aspect of the study has highlighted minor inhibitive effects of some of the reagents used in the coating formulations and a major inhibitive effect of the nano-containers. The work therefore concludes with recommendations for a possible coating formulation combining the most beneficial elements of the various coatings investigated.

▼ Concrete, a composite material consisting of aggregates bound together with cement paste, is the most widely used construction material. Concrete is relatively cheap, very versatile and has excellent compressive strength. However, its tensile strength is limited and for this reason steel rebars are often added to create reinforced concrete (RC). Cracking inevitably occurs in all RC materials and associated structures due to a variety of mechanical and environmental actions. The generation of tiny microcracks within concrete facilitates the flow of potentially aggressive fluids that can corrode the embedded steel rebars and, in extreme cases, lead to premature structural failure. Concrete, along with all cement-based materials, does possess some inherent self-healing capacity and is able to heal certain-size cracks autogenously. This self-healing capability is very limited and therefore researchers have attempted to improve upon it by using a variety of techniques. In particular, the use of engineered additions for autonomic self-healing has gained significant interest in the past two decades. An example is the addition of microcapsules that disperse throughout the hardened material subsequently providing reservoirs of healing agents. When cracks arise within the material, they rupture the embedded microcapsules causing a release of their contents into the crack volume. The released material then reacts to provide filling, sealing and healing of the crack. The primary aim of this research project was to investigate the autonomic self-healing performance of concrete containing microencapsulated sodium silicate. The effect of microcapsule addition on the fresh, hardened and self-healing properties of cement, mortar and concrete were all explored. Self-healing was monitored using a variety of techniques and results reveal the increased self-healing ability of microcapsule-containing cementitious materials as well as the efficacy of sodium silicate as a healing agent. Furthermore, the self-healing concrete field trial displays the great potential for microcapsules to be incorporated into large-scale self-healing concrete applications.

▼ Many inspiration in biological science world strike exciting opportunities in material science and led to a range of biomimetic and other advanced functional materials for engineering and medical applications. The self-controlled smart behavior of these systems make their individual functional components sense and process the environment and take necessary actions, similar to a living creature. This smart action is referred to a progressive change of material internal structure and chemical composition at a macroscopic interval of time. The dynamic internal structure results in varying constitutive properties and viewed as an adequate response of the material to external loading. The slow-rate evolution of constitutive properties of the materials is often affected by non-elastomechanical nature, such as phase transitions, chemical reactions, diffusion and other kinetic processes at the atomic scale. Additionally, the interplay between the mechanical performance and the internal structure dynamics can be two-way. This indicates that mechanical stress or strain in such material may trigger or affect kinetic processes responsible for its internal structure evolution; in turn, the changed internal structure may influence bulk properties and therefore mechanical response of the material to the external loading. In this study, a nondeterministic multiple scale approach based on numerical solution of the Monte-Carlo master equation on atomic lattices solved together with a standard vi Finite-Element formulation of solid mechanics is investigated. This approach is applicable to long-term evolutionary processes such as precipitation, volume diffusion and creep cavity self-healing in nano-crystalline austenite (Fe fcc) samples. A two-way mechanokinetic coupling is achieved through implementation of strain- dependent diffusion rates and dynamic update of the finite element model based on atomic structure evolution. This study also discusses the effect of macroscopic static loading and cavity geometry on the total healing time. The approach is used in application of modeling and characterization of advanced functional materials with evolutionary internal structures, and emerging behavior in material systems.
