Summary:

Computational simulation of metal forming processes, such as punching, impact and necking, usually require adaptive strategies for the finite element method in order to obtain accurate results. In this work, mesh adaptation is applied using the Arbitrary Lagrangian-Eulerian (ALE) formulation, which is able to relocate nodes without changing the mesh topology while keeping elements with a good shape. In addition, cases such as necking need the mesh to be concentrated in zones with high plastic deformation values. The formulation developed, using the 3-D finite element code for large deformation problems METAFOR (METAl FORming), is capable of reducing mesh distortion and concentrating nodes in critical zones. Thus, a wide variety of metal forming processes can be efficiently and precisely simulated. Some cases are presented
