Simulation of Welding Processes in Ansys LS-DYNA

This course will introduce the simulation of welding using Ansys LS-DYNA® nonlinear dynamic structural simulation software. It will cover how to define a moving welding heat source, thermal contact between welding parts, welding material models, and the general setup of a welding process. The course includes practical examples to help you become familiar with these techniques.

Learning Outcomes:

Following completion of this course, you will be able to:

• Understand the basic elements of setting up a welding simulation in LS-DYNA.
• Know how to create a moving welding heat source in LS-DYNA.
• Know how to characterize thermal contacts between welding parts.
• Understand the welding material models in LS-DYNA.
• Know how to define initial and boundary conditions for a welding simulation.
• Do a general set-up of a welding simulation.

Prerequisites:

• Completion of Introduction to Ansys LS-DYNA Software course is recommended.
• Basic understanding of welding processes

Please note: These training materials were developed and tested in the 2021R1 release.
