LS-DYNA Compact: Introduction to EFG

Structural deformations usually occur when particularly soft materials like rubber or foam are subjected to stress, or when metals are massively formed, such as during forging or extrusion. Their simulation requires numerical calculation methods that are superior to conventional methods. One of these methods is the Element Free Galerkin (EFG) method.

The participants of this webinar receive an introduction to the theoretical basics and background of the EFG method. Furthermore, the required settings in the LS-DYNA input deck, which are required for the realization of a successful nonlinear EFG simulation, will be discussed in detail.

Especially, the new possibilities of local adaptivity in combination with implicit time integration and coupling to thermal analysis are addressed. Additionally, the possibilities of fracture simulations using discontinuous EFG formulation are discussed. The course includes practical exercises to deepen the basics.

The course will take place from 9-11 a.m. (CET) on two consecutive days.
