Hi everyone,

I am modeling a tensile test with Optistruct by imposing displacements. After the analysis, the stress strain curve does not stop at the ultimate strength, but the stresses of the finite elements go on increasing. Is there a way to ensure the stresses do not exceed the ultimate strength?
