Element Types & Nonlinear Aspects

This seminar is a collection of different topics on nonlinear aspects surrounding LS-DYNA. Emphasis is directed towards element technology and the specific elements implemented in LS-DYNA. In addition, adaptive schemes for nonlinear problems are presented. Since more and more implicit features are included in LS-DYNA, another part of the class is dealing with implicit solver technology for nonlinear problems.

Contents

• Element formulations implemented in LS-DYNA
• Application field and pros/cons of the different element types
• Theoretical background of various element formulations
• General aspects of nonlinear problems in finite element theory
• Solvers for implicit analyses with specific emphasis on LS-DYNA
• Various example problems using LS-DYNA

This class is intended for participants with pre-existing knowledge in finite element technology and LS-DYNA who would like to learn more about various aspects of nonlinearities and their implementation in LS-DYNA and who are also interested to obtain better insight into the theoretical background.
