Modeling the Crushing Behavior of a Tubular Structure using the Ansys LS-DYNA Tool

This simulation tutorial aims to provide a basic introduction into running Ansys LS-DYNA®, a nonlinear dynamics structural simulation software, simulations with the help of Ansys LS-PrePost® and Ansys LS-Run capabilities. The tutorial features an example of a tubular structure with a square cross-section that is crushed against a flat, rigid plate. The tutorial is divided into four distinct topics:

  1. meshing the structure for analysis
  2. analysis setup using keywords and basic modeling aspects of the Ansys LS-DYNA tool
  3. understanding what modeling checks need to be run prior to the simulation using the Ansys LS-Run capability
  4. running post processing using some of the functionality available in the Ansys LS-PrePost capability.

An accompanying video series for all four parts can be found on the Ansys Learning YouTube Channel.
