In this project, you will understand modeling of Material LAW-1- Elastic, LAW-2, LAW36 - Elastoplastic, and LAW-27-Brittle along with Johnson-Cook failure in Radioss. You will also understand XFEM formulation to understand the effect of cracking in the model.
In this project, you will be simulating a rigid sphere impacting over a plate with Aluminium material. The plate is first investigated for the failure with XFEM and without XFEM. Then the same plate failure is studied with the EPS and Johnson-Cook failure card. After understanding these failures then the plate is modeled with the elastic material card MAT-1 and the behavior is studied. MAT-36 is used to model the plate with the help of plastic strain and stress and failure of the plate are studied. Finally, the same plate is modeled with a Brittle material MAT-27 to understand the failure effects of Brittle material. With the help of the above investigations, a clear understanding is developed on the use cases of these failure cards and the material cards.
