Assignment 4-RADIOSS Material Laws Challenge
Aim:
The aim is to analyze the given simulation for the 7 cases and compare the result.
Objective:
Case 1
- Import the FAILURE_JOHNSON_0000.rad file and run the model as it is. Give the title name as Law2_epsmax_failure.
Case 2
- Import the case 1 rad file, named “Law2_epsmax_failure” and perform the simulation with failure plastic strain (EPS_p_max) and fail_Johson card enabled.
- Changes to be made in /FAIL/JOHNSON card:
- ifail_sh= 1
- Dadv= 1
- Ixfem= 1
- Use the recommended values for the property card.
- Give the title name as Law2_epsmax_crack.
Case 3
- Import the case 2 rad file, named “Law2_epsmax_crack” and perform the simulation by removing the fail_Johnson failure card. Give the title name as Law2_epsmax_nofail.
Case 4
- Import the case 3 rad file, named “Law2_epsmax_nofail” and perform the simulation by removing both the failure plastic strain (EPS_p_max) and the fail_Jhonson failure card.
Case 5
- Import the case 4 rad file and perform the simulation by changing the material card to Law 1. Keep the same value for rho, E, and nu values.
Case 6
- Import the case 1 rad file, named “Law2_epsmax_failure” and perform the simulation with the law 36 material card. Refer to the video titled "Materials 7" for further information.

Case 7
- Open the Law27_0000.rad file and perform the simulation with the law 27 material card. Use the recommended shell properties.
Procedure:
The procedure is same for all the cases, importing the file using solver deck and changing the required condtion and run the analysis in the radioss,
