  1. Hello Everyone, I have experimental fatigue test setup for rubber components in which load is applied in cyclic manner with a non zero mean value. This test is carried for more than 72 hours. Is it possible to use optistruct for fatigue analysis of such test as mentioned in the tutorial? can anyone shed some light on it?( I am concerned about how to apply load) Or is it necessary to perform fatigue analysis? Can I replace it with say frequency response analysis or transient? Regards, Bharat
  2. I ran a simulation with a non linear material ( Having a stress strain curve data upto its ultimate tensile stress). In the simulation results, the von mises stress exceeds the limit of stress I have entered in the curve data. What is happening here? Is the software extrapolating from the data OR assuming zero resistance from the regions where the von mises stress has exceeded the ultimate limit.
