1. Amini, Keivan. Numerical Investigation into Axial Cutting of AA6061-T6 Circular Extrusions Under Blast Loading.

Degree: MA, Mechanical, Automotive, and Materials Engineering, 2012, University of Windsor

The study detailed in this thesis focuses on the force/time and energy absorption performances of circular AA6061-T6 aluminum alloy extrusions with the wall thickness of 3.175 mm and 1.587 mm subjected to cutting deformation modes under blast loading conditions. Numerical simulations of the detonation as well as the axial cutting deformation process employing an Eulerian finite element formulation and Smooth Particle Hydrodynamic (SPH) were performed. Numerical detonation models were in good agreement with experimental results having an average standard error less than 3% for impulse predictions. Good predictive capabilities of the numerical model employing the Eulerian element formulation for the axial cutting behaviours were observed, while the SPH formulation failed to predict experimentally observed deformation modes. The average mean cutting force, measured at the load cell for both experimental and numerical testing methods as a result of cutting deformation was observed to be 18.8 kN and 33.5 kN for the thin- and thick-walled extrusions, respectively. Force and energy analyses were conducted using theoretical and numerical models to study the steady-state cutting condition. Theoretically, it was observed that the friction force contributed 48% of total axial cutting resistant force, independent of extrusion wall thickness. Advisors/Committee Members: William Altenhof.

2. FERNANDES, Camila Albuquerque. Estudo do desempenho mecânico e microestrutural de uniões da liga de alumínio, AA6061-T6, por solda a ponto por fricção (FSpW).

Degree: 2016, Federal University of Pernambuco

Solda a Ponto por Fricção (Friction Spot Welding – FSpW) é um processo relativamente novo de soldagem desenvolvido e patenteado pelo GKSS na Alemanha, que visa complementar e/ou substituir tecnologias de uniões de soldagem convencionais. Essa nova tecnologia de soldagem se dá pela união no estado sólido, onde duas ou mais chapas são unidas através da transferência de energia térmica e mecânica que é gerada pela rotação da ferramenta. O presente trabalho visou avaliar a aplicabilidade da união da liga de alumínio 6061-T6 pela técnica de Solda a Ponto por Fricção. Essas soldas foram produzidas em configuração de sobreposição utilizando condições de soldagens variadas, por meio de diferentes combinações de velocidade de rotação, profundidade de penetração e velocidade de penetração; os quais foram estabelecidos através de uma análise estatística, utilizando como ferramenta o Box-Behnken. A integridade da junta soldada foi avaliada através dos efeitos dos parâmetros de processo, na geometria e na microestrutura da junta, e também no desempenho mecânico. Realizou-se também a otimização do processo de soldagem e um estudo sobre o comportamento de fratura das soldas submetidas a um esforço de cisalhamento. Os resultados mostraram que a melhor combinação de parâmetros foi encontrada na condição de soldagem: 130 rpm, 4,0 mm/s e 1,4 mm, com um valor médio de resistência ao cisalhamento de 6243,29 N, com boa reprodutibilidade. O botão da solda é constituído por três elementos geométricos que se mostraram inerentes ao processo: cunha, união principal e união secundária. Estes elementos mostraram possuir forte influência sobre o desempenho mecânico.

Friction Spot Welding (FSpW) is a relatively new welding process patented by GKSS in Germany. This new welding technology is given by the joining in a solid state, in which two or more plates are joined by thermal and mechanical energy transfer that is generated by the rotation of the welding tool. The aim of this work is to study the integrity of the welds of AA6061-T6, by the FSpW process. These welds were produced in an overlapping configuration using different welding conditions, through different combinations of rotational speed, depth of penetration and penetration speed, which were set through a statistical approach using the Box-Behnken. The integrity of the welded joint was evaluated by the effects of process parameters on geometry and microstructure of the joint, and also in the mechanical performance. It was also performed the optimization of the welding process and a brief study on the fracture behavior of the welds subjected to a shear stress. The results showed that the best combination of parameters was found in the welding condition: 130 rpm 4.0 mm / s and 1.4 mm with an average value of the shear strength of 6243.29 N, with good reproducibility. The metallurgical investigation revealed three geometric elements that are inherent to the process: primary union and secondary union and hook. These elements were shown to have strong…

3. Ganesh P. Studies on experimental numerical and finite element analysis of superplastic forming on friction stir welded AA6061 T6 alloy;.

Degree: Studies on experimental numerical and finite element analysis of superplastic forming on friction stir welded AA6061 T6 alloy, 2014, Anna University

Superplastic forming process is one of the metal forming processes widely used in the manufacture of components for aerospace and automobile application Friction stir welding is one of the solid state welding process where the resulting joint is strong and more reliable than traditional welding joints The friction stir welding process retains the fine grained microstructure of the parent material and helps the superplastic forming process Superplastic forming requires a fine grained microstructure to induce the newlinedeformation mechanism of the grain boundary sliding Some of the problems encountered during friction stir welding to retain the superplasticity in the material are superplasticity of friction stir welded joints can be influenced by the welding process parameters such as spindle speed and feed rate friction stir welding produced continuous dynamic recrystallization in the weld nugget zone with fine grained microstructure which enable the deformation mechanism of grain boundary sliding, and major defects such as tunneling warm hole porosity and cavitations are likely to occur during friction stir welding newline
