Element Free Galerkin Method (EFG) is applied for the materials made of rubber or foam that undergo large deformations. The adaptive EFG formulation is the method of choice for the efficient simulation of cutting, bulk forming and forging processes. In particular, the new features of local mesh refinement in combination with the implicit time integration are the key enablers for these processes.

This LS-DYNA example shows the bulk metal cutting process using the Element Free Galerkin Method (EFG).  …more
