Ces travaux de thèse sont dédiés à la mesure de formes 3D, de champs cinématiques 3D surfaciques et à l'identification de paramètres mécaniques à partir de mesures par corrélation d'images. Cette méthode optique se base sur l'utilisation de caméras comme support de la mesure. Pour cette raison, une étude des différents modèles de caméra classiquement utilisés est effectuée, puis le passage d'un formalisme continu pour la description des images à une approche discrète utilisant la notion de pixel est décrit. Une attention particulière est portée aux distorsions optiques et une approche utilisant la corrélation d'images pour les évaluer est développée. Une nouvelle méthode de mesure de forme 3D et de champs de déplacements 3D surfaciques par stéréo-corrélation d'images est introduite. Elle utilise un modèle numérique de l'objet observé comme support pour la corrélation. Cette méthode mène à une formulation globale de la stéréo-corrélation. Elle peut être écrite dans le cas général et particularisée à des surfaces NURBS (non-uniform rational B-splines). Le champ de déplacement est également exprimé dans un formalisme NURBS complètement cohérent avec le modèle géométrique utilisé pour définir la forme observée. Des mesures sont validées en utilisant des mouvements imposés à un carreau de Bézier usiné. La faisabilité de la technique dans plusieurs cas industriels est également étudiée avec, par exemple, la mesure des déplacements d'une pièce composite de train d'atterrissage chargée mécaniquement. Enfin, à partir de cette formulation isogéométrique de la mesure de champs, une étude de la caractérisation de propriétés élastiques est effectuée. Deux méthodes inspirées d'approches existantes sont ainsi proposées, utilisant des mesures de champs et des calculs numériques dans un formalisme isogéométrique pour identifier des paramètres de loi de comportement élastique isotrope sur un cas test numérique et pour un essai de traction uniaxiale.

This thesis is dedicated to measurement of 3D shapes, 3D kinematic fields on surfaces and identification of mechanical properties from digital image correlation measurements. This optical method uses cameras as measurement tools. For this reason, a study of the classical camera models used is performed and the description of the digitalization of an image from a continuous to a discrete formalism using the pixel is described. A specific work is dedicated to optical distortions and a method based on digital image correlation to evaluate these distortions is developped.A new method for 3D shapes and 3D displacement fields on surfaces using stereo-correlation is introduced. A numerical description of the observed object is used as a support to perform the correlation. This method lead to a global approach to stereo-correlation. It can be rewrite in a generic case or in particular to be applied to NURBS (Non-Uniform Rational B-Splines) surfaces. The displacement fields is therefore expressed in a NURBS formalism which is completely consistent with the geometrical model used to described the…

▼ [ES] La interacción de contacto entre sólidos deformables es uno de los fenómenos más complejos en el ámbito de la mecánica computacional. La resolución de este problema requiere de algoritmos robustos para el tratamiento de no linealidades geométricas. El Método de Elementos Finitos (MEF) es uno de los más utilizados para el diseño de componentes mecánicos, incluyendo la solución de problemas de contacto. En este método el coste asociado al proceso de discretización (generación de malla) está directamente vinculado a la definición del contorno a modelar, lo cual dificulta la introducción en la simulación de superficies complejas, como las superficies NURBS, cada vez más utilizadas en el diseño de componentes. Esta tesis está basada en el "Cartesian grid Finite Element Method" (cgFEM). En esta metodología, encuadrada en la categoría de métodos "Immersed Boundary", se extiende el problema a un dominio de aproximación (cuyo mallado es sencillo de generar) que contiene al dominio de análisis completamente en su interior. Al desvincular la discretización de la definición del contorno del problema se reduce drásticamente el coste de generación de malla. Es por ello que el método cgFEM es una herramienta adecuada para la resolución de problemas en los que es necesario modificar la geometría múltiples veces, como el problema de optimización de forma o la simulación de desgaste. El método cgFEM permite también crear de manera automática y eficiente modelos de Elementos Finitos a partir de imágenes médicas. La introducción de restricciones de contacto habilitaría la posibilidad de considerar los diferentes estados de integración implante-tejido en procesos de optimización personalizada de implantes. Así, en esta tesis se desarrolla una formulación para resolver problemas de contacto 3D con el método cgFEM, considerando tanto modelos de contacto sin fricción como problemas con rozamiento de Coulomb. La ausencia de nodos en el contorno en cgFEM impide la aplicación de métodos tradicionales para imponer las restricciones de contacto, por lo que se ha desarrollado una formulación estabilizada que hace uso de un campo de tensiones recuperado para asegurar la estabilidad del método. Para una mayor precisión de la solución, se ha introducido la definición analítica de las superficies en contacto en la formulación propuesta. Además, se propone la mejora de la robustez de la metodología cgFEM en dos aspectos: el control del mal condicionamiento del problema numérico mediante un método estabilizado, y la mejora del campo de tensiones recuperado, utilizado en el proceso de estimación de error. La metodología propuesta se ha validado a través de diversos ejemplos numéricos presentados en la tesis, mostrando el gran potencial de cgFEM en este tipo de problemas.; [CAT] La interacció de contacte entre sòlids deformables és un dels fenòmens més complexos en l'àmbit de la mecànica computacional.

Hoje em dia, a crescente demanda por produtos com alta exatidão dimensional e geométrica tem exigido tolerâncias cada vez mais estreitas. Adicionalmente, peças de geometrias complexas e formas livres tem sido uma prática comum em indústrias dos setores automotivos, aeronáuticos, bioengenharia dentre outros. Para atender as estas demandas se faz necessário sistemas de inspeção cada vez mais exatos e flexíveis. As Máquinas de Medição por Coordenadas (MMCs) são uma importante ferramenta no processo de concepção, fabricação e inspeção dos produtos manufaturados nos dias de hoje. Para identificar as mais diversas formas e características das superfícies existem várias técnicas, tais como, superfícies Bézier, Splines, B-Splines, e NURBS (Non- Uniform Rational B-splines). As NURBS são uma ferramenta importante e uma grande aliada na modelagem de formas geométricas complexas, dando significativas contribuições na engenharia reversa. Sem dúvida, a exatidão do processo de modelagem de uma peça será tão maior quanto maior for o número de pontos coletados ou medidos sobre a sua superfície (seja por uso de laser ou escaneamento contínuo por contato ou por contato ponto a ponto). Então, o principal objetivo desta tese é desenvolver e implementar uma nova metodologia para modelagem de superfícies de formas livres e geometrias complexas utilizando a técnica NURBS em MMC com apalpador touch trigger. Também, foi desenvolvida uma estratégia de medição para obtenção de pontos sobre a superfície estudada. A metodologia proposta foi aplicada experimentalmente para a obtenção de um perfil evolvental de uma engrenagem cilíndrica de dentes retos, um modelo físico reduzido de um avião e um capacete de ciclista. Os resultados obtidos tanto por simulação quanto experimentalmente mostraram a relevância da metodologia desenvolvida.

Nowadays the increasing demand for products with high dimensional accuracy and geometric measures has required increasingly accurate. It is necessary to use inspection systems more accurate and flexible to expect these demands. The Coordinate Measuring Machines (CMMs) are an important tool in the design, fabrication and inspection of products manufactured today. These machines are used by the engineer, whose main purpose is to produce an accurate digital model in a virtual space for later use in CAD / CAE / CAM / CAI. To identify the several shapes and surface features, there are many techniques such as Bezier surfaces, splines, B-Splines and NURBS (Non-Rational B-Splines). The NURBS present many advantages, simplicity and facility of data handling, which tends to minimize the problems of randomness and inaccuracy of the cloud of points obtained by the CMM. Thus, the NURBS are an important tool for modeling free-form, making significant contributions in reverse engineering. It is known however that the accuracy of the modeling process of a piece will be greater the larger the number of points collected or measured on the surface (whether by use of laser or continuous scanning by contact or touch point to point).…

▼ A instalação de dutos flexíveis em ambiente submarino de alta profundidade é realizada recorrentemente pelas indústrias de óleo e gás. Estes dutos transportam fluidos como água, gases e óleo. Durante o minucioso processo de instalação dos dutos flexíveis, é necessário o monitoramento constante de sua geometria a fim de evitar a propagação de esforços e consequentemente danos aos equipamentos envolvidos. Para que este monitoramento seja eficiente, podem ser utilizadas técnicas de reconstrução 3D que usam como entrada as imagens capturadas por um par de câmeras estéreo instaladas nos robôs que acompanham a operação. Esta dissertação de mestrado propõe o desenvolvimento dos algoritmos de rastreamento e reconstrução para dutos flexíveis com o intuito de permitir o monitoramento em tempo real da operação. O algoritmo de rastreamento proposto tem a função de determinar um conjunto de pontos que representam a projeção do eixo medial do duto em cada imagem do par estéreo. Para alcançar esse objetivo, o algoritmo utiliza características da iluminação em ambientes submarinos e de marcações realizadas no duto. A etapa de reconstrução utiliza os pontos rastreados para estimar uma curva B-spline racional não-uniforme (NURBS) sobre um plano tridimensional. Essa aproximação simplifica o processo de reconstrução e permite obter resultados mais precisos. Experimentos realizados em ambiente aquático e aéreo, utilizando uma escala reduzida, permitiram uma análise da acurácia e robustez dos algoritmos propostos. O erro médio alcançado foi menor que meio centímetro em todos os casos analisados. Além disso, concluiu-se que a disposição dos pontos da curva e a posição do plano influenciam na estimativa da reconstrução. Testes com imagens reais da operação foram também realizados e permitiram validar as técnicas propostas neste ambiente. Os resultados obtidos foram robustos em casos de baixa iluminação, ruidosos e com elevada obliquidade. Os métodos propostos são eficientes computacionalmente e permitem a obtenção do resultado a uma taxa superior a 30 quadros por segundo.

La Conception Assistée par Ordinateur (C.A.O) qui permet de concevoir des objets physiques à partir de modèles mathématiques est utilisée dans de nombreux secteurs de l’industrie.On constate actuellement une volonté généralisée de tirer parti de deux approches jusqu’à présent plutôt antagonistes : la modélisation géométrique continue qui crée des objets continus représentant par la modélisation à partir de surfaces B-splines ou NURBS) et la modélisation géométrique discrète qui qu’il s’agisse de maillages ou de surfaces de subdivision.Cette dualité d’approche a de nombreuses applications industrielles potentielles et présente donc un intérêt scientifique important. Les surfaces polyédriques et en particulier les surfaces de subdivision offrent intrinsèquement la discrétisation, sont d’une manipulation très simple, mais elles ne remplacent pas les surfaces B-splines ou NURBS. Les travaux présentés dans la thèse et qui ont abouti au passage réciproque d’une surface paramétrique à une surface polyédrique. Nous nous intéressons plus particulière aux surfaces de subdivision considérant comme une liaison entre la surface polyédriquee et la surface paramétrique parce qu’après quelques étapes de subdivision, le polyèdre caractéristique converge à une surface paramétrique correspondant. Nous y proposons des schémas de la subdivision inverse permettent de récréer les surface polyédrique grossier de subdivision précédent. Nous avons donc développé deux méthodes pour la reconstruction d’une courbe/surface paramétrique en utilisant le schéma de subdivision inverse uniforme et le schéma de subdivision inverse non-uniforme. Pour améliorer les résultats de reconstruction par la subdivision inverse, nous associons à ces méthodes une possibilité d’ajustement d’approximation qui permet de diminuer grandement l’erreur de reconstruction. Les résultats obtenus ont été comparés à une méthode bien connu de reconstruction sens au sens des moindres carrés. Nos méthodes sont très prometteuses en termes d’approximation et de compression

Computer Aided Geometric Design (CAGD) which allows us to design the physical objects from mathematical models is used in many sectors of industry. It is currently a general wish to take advantage of the two these approaches rather than the antagonists : The goal that the continuous geometric model creates the continuous objects represented by the modelof the surfaces B-splines or NURBS) and the discreet geometric model made by eitherthe meshes or the subdivision surfaces. This duality of the approach has many potential industrial applications and therefore submits interesting significant science. The polyhedral surfaces and the subdivision surfaces in particular which offer the intrinsically discretization,are a very simple manipulation, but they do not replace the surfaces B-splines or NURBS.The works presented in this thesis aim to the reciprocal passage from a parametric surfaceto a polyhedral surface. We are more specialy interested to subdivisions surfaces considering as a liaison between the polyhedral…

Les réservoirs clastiques sont constitués pour la plupart d'un agencement géométrique de plusieurs structures. Le but de ces travaux est de fournir une représentation volumétrique de ces différents objets afin de pouvoir reproduire la grande hétérogénéité des dépôts sédimentaires. Nous proposons une paramétrisation tridimensionnelle compacte des objets sédimentaires qui permet de représenter des géométries variées et qui fournit un espace curvilinéaire pour la modélisation des hétérogénéités internes des structures sédimentaires. Les modèles de corps géologiques sont définis par une représentation par frontières, chacune des frontières étant construite par une surface paramétrique déformable. La formulation mathématique utilisée pour construire les espaces paramétriques sont les B-Splines rationnelles non uniformes dites NURBS (pour Non Uniform Rational B-Splines). Chaque forme élémentaire est contrôlée par des règles de déformations afin de maintenir la géométrie et la cohérence des objets durant l'édition. Les modèles de structures sédimentaires sont appliqués à la simulation de chenaux et des structures qui y sont liées telles que les barres d'accrétion latérale. Ils servent alors de support pour réaliser des simulations de propriétés pétrophysiques qui suivent l'espace paramétrique particulier de chaque objet. Les modèles d'objets sédimentaires sont également appliqués dans le cadre de l'interprétation semi-automatique d'images géologiques en adaptant des méthodes classiques d'extraction de formes. Cette approche est appliquée sur des images satellites de chenaux alluviaux. Des résultats préliminaires sur des données de sismiques 3D sont également présentés

Most clastic deposits consist in geometric arrangements of several structures. The purpose of this work is to provide a volumetric representation of these objects in order to reproduce the high heterogeneity of the sedimentary deposits. These models are constructed to be flexible and compact in order to model the sedimentary formations at different scales. The sedimentary models are defined by a boundary representation ; each boundary is defined by a deformable parametric surface. The proposed parametrization is the Non Uniform Rational B-Spline (NURBS). Each elementary shape is controlled by deformation rules and has connection constraints with associated objects, in order to maintain the geometry and the consistency through editing. Sedimentary structure models are applied to channel simulation and to the construction of the related structures such as point bars. These structures are then used as framework for petrophysical property simulations. The models are also applied to semi-automatically interpret geological images by adapting classical shape extraction methods. This approach is applied on satellite pictures showing alluvial channels and some preliminary results on 3D seismic time slices are also presented

▼ This thesis describes new parallel GPU algorithms that accelerate fundamental CAD operations such as spline evaluations, surface-surface intersections, minimum distance computations, moment computations, etc., thereby improving the interactivity of a CAD system.CAD systems (such as SolidWorks, AutoCAD, ProE, etc.) create graphical user interfaces for solid modeling, which build on fundamental CAD operations that are performed by a modeling kernel. However, since many of these fundamental operations are compute-intensive, the CAD systems make the designer wait until a particular operation is completed before providing visual feedback and allowing new operations to be performed, reducing interactivity. The broad objective of this research is to develop new parallel algorithms for CAD that run on Graphics Processing Units to provide order-of-magnitude better performance than current CPU implementations.A critical operation that all CAD systems have to perform is the evaluation of Non-Uniform Rational B-Splines (NURBS) surfaces. We developed a unified parallel algorithm to evaluate and render a NURBS surface directly using the GPU. The GPU algorithm can render over 100 NURBS surfaces at 30 frames per second, significantly enhancing interactivity.Fundamental modeling operations (such as surface intersections, separation distance computations, etc.) are typically performed repeatedly in a CAD system during modeling. We have developed GPU-accelerated algorithms that perform surface-surface intersections more than 50 times faster than the commercial solid modeling kernel ACIS. We have also developed GPU algorithms to perform minimum distance computations, which have applications in multi-axis machining, path planning, and clearance analysis. These algorithms are not only more than two orders of magnitude faster than the CPU implementations, they often have much tighter error bounds.We have also developed algorithms for computing accurate geometric moments of solid models that are represented using multiple trimmed-NURBS surfaces. We have developed a framework that makes use of NURBS surface data to evaluate surface integrals of trimmed NURBS surfaces in real time. With our framework, we can compute volume and moments of solid models with error estimates. The framework also supports local geometry changes, which is useful for providing interactive feedback to the designer while the solid model is being designed.Finally, the ultimate objective of this research is to provide a generalized framework to overcome some of the GPU programming challenges in CAD. Using this framework, a programmer could easily develop complex CAD algorithms that utilize the GPU to improve the performance of CAD systems.

▼ Generalized finite element methods have proved a great potential in the mesh-independent modeling of both weak and strong discontinuities, such as the ones encountered when treating materials with inclusions or cracks. By removing the constraint of a conforming mesh, more freedom is offered to modeling exact geometries by means of splines. However, very few studies have been published which combine Non-Uniform Rational B-Splines (NURBS) to interface-enriched methods, addressing uniquely weak discontinuities. Therefore, the aim of this thesis is to propose a NURBS-based enhancement to the Discontinuity-Enriched Finite Element Method (DE-FEM) in two dimensions and to discuss the potential of its application. The main advantage of this method is the possibility to study problems that present discontinuities with arbitrary smooth shapes, while maintaining exact geometries throughout the analysis: in this way, the equivalence between design and computational geometry is preserved. To this purpose, a suitable NURBS-based analysis technique is selected and implemented within the framework offered by the group's finite element library, Hybrida. The capabilities of the NURBS-enhanced DE-FEM to solve several weakly discontinuous problems are assessed for composites of different complexities. Furthermore, a novel study is presented which extends this technique to the treatment of strong discontinuities, in the context of fracture mechanics. The accuracy, convergence properties and numerical efficiency of the proposed method are investigated, in particular in comparison with the standard DE-FEM. Based on these observations, further insights are provided into the convenience and the limitations of adopting NURBS enhancements within the DE-FEM formulation. Lastly, some recommendations about possible directions of improvement are provided.
