Objective
Discuss all contact types in LSDYNA. Learn how to define contact and how contact works in LS-DYNA to solve engineering problems. Examples are used to illustrate the points made in the lectures.
Audience
This course is recommended for engineers who want to understand and better define contact surfaces in LS-DYNA to run problems involve crash and impact simulations. This course is useful for engineers and researchers who are working in the area of crashworthiness, general impact and drop simulation, and other problems that involved defining contact surfaces.
