I perform a non-linear quasi-static analysis in OptiStruct where an impact element penetrates and expands a composite tube. This tube consists of 3 layers. Because each layer will fail at a different laod, I want to apply a stress-strain curve. This curve should fall on a low stress level (not zero) after the element fail.…
