LS-DYNA, Simulation of sheet metal forming processes

This 3-day course is intended for people who want to use LS-DYNA for metal forming simulations. The course will cover how different aspects of metal forming processes are modeled in LS-DYNA and how to do this as accurate and efficiently as possible. The attendee will acquire deep knowledge in settings and techniques in several parts of LS-DYNA which will be beneficial for his/hers daily work and future applications.

It is beneficial if the attendees have basic knowledge of FE simulations and LS-DYNA. LS-PREPOST will be used as a pre/post processor but Dynaform is an alternative if requested by the attendees.
