Improving numerical simulation of metal forming processes using adaptive remeshing technique

Numerical simulation by finite element of forming processes requires ductile damage. In this context, problems of meshing and remeshing often impede the convergence of the processes and frequent remeshing must be performed in order to avoid severe mesh distortions while adapting the mesh size to the solution (plasticity, damage, temperature). Solutions to this problems are proposed in this paper. Geometrically and physically error estimators have also been developed in order to locate areas where a remeshing is needed. This adaptive scheme has been coupled to ABAQUS/Explicit solver.
