Using the Implicit Capabilities of LS-DYNA

Given by Morten Jensen of LSTC

Duration: 2 Days

Objective of the course:

The attendee will learn how to run LS-DYNA® implicit for linear and non-linear static and dynamic analysis. Detailed descriptions of the input required for an implicit deck are given and additional implicit features are presented. The class will show the areas where the explicit and implicit solver differs, e.g. is show unsupported features for the implicit code. Some of the latest features for the implicit solver are also shown. There will be several examples that the user will run in a workshop. These examples are designed to understand and reinforce the lectures. The course is practical oriented towards LS-DYNA® it is not a theoretical course.

Course Content:

• Introduction to LS-DYNA®'s capabilities
• Current Implicit capabilities
• Explicit version Implicit integration
• Activation of the implicit solver
• Implicit linear and non-linear static analysis
• Implicit linear and non-linear dynamic analysis
• Contact specification
• Choice of material and elements
• Explicit - implicit switching
• Springback in metal forming
• Eigenvalue analysis
• Buckling analysis
• Convergence problems
• Practical guidelines

Instructor:

Dr. Morten Rikard Jensen graduated from Aalborg University, Denmark in 1995 with a master degree in Manufacturing Engineering and he obtained his Ph.D. in Mechanical Engineering at the same University in 1999. His main area has been experimental work on sheet metal forming, especially determination of tool wear and investigation of the hydromechanical deep drawing process. Besides experimental work Dr. Jensen has worked extensively with the Finite Element code LS-DYNA® since 1994.

Dr. Jensen has published 10 papers in international journals, more than 15 papers in international conferences and about 25 additional papers.

Dr. Jensen has since 2001 worked at Livermore Software Technology Corporation as a support and project engineer, supervising customers in the use of the Finite Element code LS-DYNA®, the pre/post processor LS-PREPOST® and the optimization code LS-OPT®. Dr. Jensens work covers all main areas of the LS-DYNA® code, e.g. crash simulation, metal forming, bullet penetration, explosion etc.
