Hi everyone, I want to use nonlinear material for my drop test. i have stress - strain curve. i want to know how can this be brought into Radioss ? also I want to have plastic strain among the results , i cannot find strain variable on anim tab . please let me how can i have plastic strain as result.
Hey, I tried to do to NL elastic Simulation. (followed the steps from the video https://altairuniversity.com/analysis/structural/nonlinear/nlstat-tutorial-pressure-load-on-a-chair/) but I don't get convergence. The model works actually with elastic material law. So I don't know what I have to change. Can someone have a look, please?) Furthermore, I just have the "yield strength", "ultimate strength" and "elongation at break". so actually it would be enough to put a bilinear material law. is that somehow possible or is there just the way with the table?
Hello everyone. I got some pretty strange behaviour of my Solution. 1. The canister seems to float away since the displaced surface at the bottom belongs to the canister 2. The canister itself moves up/down to the plates. In fact it stretches against the plates. general Model: I try to simulate the pressure of the upper plate on the canister, which is limited by the solid lower plate. The Model file is in the attachement. Thanks for your help P.S.: I'm pretty much a beginner in Hypermesh/Optistruct 1mmModelV1.hm
