Hi everyone!! I ask for help because I should reproduce a traction test on Patran / Nastran, to verify that the sigma / epsilon curve I entered as Field is actually the one reproduced by the simulator, I would like to verify it through a graph of the final results between stress tensor / deformation . To do this I did:
- made a parallelepiped shaped specimen
- created field
- given the characteristics to the linear elastic and elastoplastic material with the field
-constrained one side of the parallelepiped
-applied pressure to the opposite side so as to keep the specimen in traction
-mesh
- results and graph, but I always get a linear graph, although I have inserted the complete curve up to break.
I did everything with a non-linear SOL400 analysis.
Would you have any suggestions to be able to get the complete curve ??
