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. image

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
