Non-Linear Implicit Analysis in LS-DYNA- ONLINE TRAINING

LS-DYNA, the state-of-the-art explicit finite element (FE) program for large deformation mechanics, has also extensive capabilities for solving implicit type of problems. This course presents a theoretical and practical introduction to the implicit capabilities in LS-DYNA with a focus on structural analysis. The course is suited for users with at least some previous experience from using LS-DYNA for explicit analyses or for experienced users of other implicit FE-programs.
