I tried to perform tensile test in Deform 3D software but I faced some problems. Let me tell step by step.

Inputs given in tensile tests are

1. Elastic properties, 2. Plastic properties (Stress strain graph), 3. Failure criteria (Cockroft and latham failure criteria)

I have made one side (face) of tensile sample fixed and applied a constant velocity on the other side (opposite face) same as in experiment. I observed that very little thinning occurred near the opposite face where velocity was applied which was not matching with the experimental one (actually, failure location is close to centre). Also, No Effective strain contour generated during the simulation. Can anybody help me out in this ??

Consider this as urgent.
