Introduction to Contact in LS-DYNA

LS-DYNA offers extensive possibilities to model contact. In total there are more than 70 different contact types available and each type supports numerous special settings. While this generous selection guarantees extreme flexibility for the contact definition, it also requires some knowledge on the user's end to select the best possible contact definition for the problem to be solved.

The objective of this seminar is to provide the user with a summary of the possibilities and limits of the various contact formulations. In particular, the discussion focuses on the most frequentlty used contact types and their suitable applications. Herein, the effects of the various contact options on the simulation results are explained with examples.

Some LS-DYNA beginners knowledge is required to follow the workshop examples. Prior attendance of the seminar "Introduction to LS-DYNA" is therefore recommended.
