Event 07: Computational Techniques for Plasticity

The use of numerical techniques is essential for solving problem involving complex geometry and including non-linear geometrical and material behaviour and such computations are being increasingly undertaken in industrial and research environments. The continuing advances in workstation technology and future hardware developments will accelerate the acceptance of such numerical techniques for commercial analysis and design. There have been significant advances in the last few years in the development of robust and efficient solution procedures for elasto-plastic problems. In particular, the treatment of finite strain plasticity problems has reached a sufficient stage of maturity for the solution of practical problems to be undertaken with confidence. The course considered rate independent (quasi-static) and rate dependent (viscoplastic and dynamic) situations for both infinitesimal and finite strain conditions. In addition to establishing the fundamental theoretical expressions in a form suitable for numerical implementation, emphasis was placed on the development and implementation of consistently linearised algorithms to ensure quadratic convergence rates. Other topics associated with the simulation of practical problems are covered; including contact/friction modelling, damage evolution, advanced constitutive models and adaptive meshing concepts. The course also provided a short introduction to the topic of discrete elements which, when used in conjunction with conventional finite elements, provide a powerful procedure for several important classes of problems, such as multi-fracturing solids. Consideration was given to the practical difficulties encountered in the solution of industrial problems and time was devoted to general discussion and the provision of specific problem advice.

Fellowships

21 EU fellowships (18 Group 1, 2 Group 2, and 1 Group 3) were offered to young participants to attend the course.
