Hi,

I am trying to do an analysis on the dynamic stiffness of rubber with ANSYS.The model is a bushing under a cyclic load with a specified frequency,and the material damp is been considered.The loading condition simulated the testing process,but I couldn't get the hysteresis loop as the testing produces.I don't know why.

It's said ABAQUS is perfect for rubber simulation.I am just beginner on it.What should I do if I need to calculate the dynamic stiffness curve by ABAQUS?I would be grateful for your suggestions.

Thanks.
