The JOHNSON-HOLMQUIST-CONCRETE material law is a very interesting material law for concrete modeling, especially for defense applications. This material law has been implemented in Radioss V2024.1. This material law is available with the non-local regularization; this is particulary interesting to have mesh-independant damage patterns. The documentation of this material law is avalable here: https://2024.help.altair.com/2024.1/hwsolvers/rad/topics/solvers/rad/mat_law126_johnson_holmquist_concrete_starter_r.htm 

The goal of this article is to share the validation study of the JOHNSON-HOLMQUIST-CONCRETE material law. 

This article includes:

• 1 ready-to-use Altair Radioss model of balistic perforation
  
  • Altair HyperMesh version is V2024.
  • Altair Radioss version is V2024.1.
  • The Unit System is in g, mm, ms
• Altair HyperWorks session files to allow fast analysis of the simulation
• A validation report with:
  
  • an explanation of the material model
  • a verification study
  • the validation study
    • Explanation of the validation strategy
    • Description of the model setup
    • Overview of the Results & comparison with test results
    • Evaluation of the influence of the non-local regularization
