Meshfree EFG, SPG, Advanced FE

Particular attention is drawn on the application of the meshless method “Element-Free Galerkin” (EFG) as well as the newly developed method “Smoothed Particle Galerkin” (SPG). The seminar will thoroughly refer to the settings required in the LS-DYNA input deck to carry out a successful nonlinear meshfree or advanced FEM simulation. Herein, the difference between the conventional EFG and SPG formulations and the adaptive or discontinuous formulations will be explained.

Common applications of these methods are 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. Moreover, fracture simulations can be carried using the discontinuous EFG formulation.
