Overview of Contacts in LS-DYNA
In general, modeling contact in LS-DYNA is straightforward for many users and the typical contact definitions that are discussed in the introductory class to LS-DYNA perfectly suits their needs. But for expert users, LS-DYNA offers extensive possibilities to enhance contact modelling in their applications. In particular, LS-DYNA has more than 70 different contact types, and each type supports numerous options and special settings. While this generous selection guarantees extreme flexibility for the contact definition, it also requires a great deal of knowledge on the user's side to make proper use of it.
This class provides you with a summary of the possibilities and limits of frequently used contact definitions and their options when modeling contact in LS-DYNA. It focuses on a selection of suitable contact types for crash and impact dominated problems. Contact definitions used in manufacturing will be briefly mentioned but the interested user is referred to the specialized classes on these topics. During the class, workshop examples aid in explaining the effects of the discussed contact types and options on the simulation results.
- Understanding of all contact types in LS-DYNA
