Automated Adaptive Forming Simulations

In this study, an automated adaptive mesh control scheme, based on local mesh modifications, is developed for the finite element simulations of 3D metal forming processes. Error indicators are used to control the mesh discretization errors, and a consecutive h-adaptive procedure is conducted. The mesh size field used in the h-adaptive procedure is processed to control the geometric approximation errors on the evolving workpiece boundary mesh. During the simulations the workpiece mesh is adaptively enriched whenever the mesh is no longer acceptable. Industrial problems are investigated to demonstrate the capabilities of the developed scheme.
