Adaptive Refinement procedure For Sheet metal Forming
Résumé
In the numerical simulation of the forming process, we need to consider the adaptive meshing problem for a domain that has a moving tool boundary contact, damaged element, and finite deformations. During the simulation, the region ahead of the tool moving boundary needs to be refined (to satisfy stronger numerical conditions and tool shape), and the submesh in the region behind the moving boundary contact should be coarsened (to reduce the mesh size). We present a new scheme for simultaneously refining and coarsening a mesh during deep‐drawing process.
