LS-DYNA TUTORIAL 7: Hollow Tube Impact on a Rigid Wall
This is the second time uploading this video after audio enhancement.
It's been a while since my last tutorial...life got into the way but I am back!
In this tutorial, we are doing a high velocity impact problem. The T-shape made of two square tubes is impacted on a rigid wall.
Topics covered, including but not limited to:
How to use Johnson Cook material model for shell and solid elements. Failure not included, it will be the topic of another video.
How to create a square tube mesh and rotate/translate mesh
How to link/attach parts with Constrained Nodal Rigid Body/Generalized Spot weld
How to make a planer rigid wall and extract its reaction forces
Thermomechanical response of AL-6XN stainless streel over a wide range of strain rates and temperatures

Optional strain rate forms for the Johnson cook constitutive model and the role of the parameter epsilon
