The field of Nonlinear Computational Mechanics has grown very rapidly during the last decade. Due to the dramatic power increase of computers and workstations, research is very active. On the other hand, the development of robust and user friendly engineering softwares allows a wide range of applications in industry. The course presents an overview of the classical models and of the numerical methods used in the area, and shows how they can be applied in practical cases. Theory includes material and geometrical nonlinearities, and the numerical implementation in computer codes. Applications are taken from classical domains like aeronautical, spatial or car industry, but also from microelectronics, the field of energy for sustainable development, biomaterials, etc...
Computer training is scheduled in the course. Students will be invited to choose their style: as developpers, they will have the opportunity to introduce new features in a selected finite element code; as user, they will have to perform finite element analyses on simple case studies involving material and/or geometrical nonlinearities.
Expected results: After the course, attendants should have a good knowledge of some basic aspects in mechanics of material, including the material constitutive equations, the numerical algorithms and the finite element procedures. They will have the ability :
• to choose a material model and the proper procedure to identify the material parameters from experiment;
• to perform calculations of the stress or temperature fields in nonlinear cases, and to successfully manage the iterative processes associated to nonlinearities;
• to deal with contact problems;
• to evaluate the quality of a FE result obtained with a nonlinear computation (mesh sensitivity, numerical integration).
