Design of processes and products through simulation of three-dimensional extrusion

Abstract

In this work, various industrial extrusion problems with high complexity are simulated by employing efficient numerical schemes such as the arbitrary Lagrangian-Eulerian FEM and mismatching refinement with domain decomposition. And a new methodology of shape optimization technique to reduce computation time for the design of the extrusion process is introduced. The mechanical properties like anisotropy of extruded products are also analyzed by the continuum approach and discussed for practical examples, and the texture development and mechanical properties in the aluminum extrusion processes are predicted by employing a rate-independent crystal plasticity model based on the smooth yield surface with rounded-off corners.
