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.
