Advanced Computational Techniques for the Design of Deformation Processes

Nicholas Zabaras, Shankar Ganapathysubramanian


A number of recent advances towards the development of a robust computational design Lagrangian FEM simulator for multi-stage metal forming processes will be presented. A continuum parameter and shape sensitivity analysis is being developed for metal forming processes using an updated Lagrangian framework suitable for very large deformations when re-meshing operations are performed during the analysis. A regularized sensitivity contact algorithm is introduced together with a consistent finite element treatment of near incompressibility. The effectiveness of these design techniques will be demonstrated with various applications in the design optimization of metal forming processes.
