    Hi,

     

    Can you let us know what the use case?

     

    What is the analysis about and what type of analysis?

     

    You can use PBUSHT elements with type as KN to give force Vs deflection curve.

    Thanks for your answering my question!

    In fact I have built a bush element to simulate the rubber with force-deflection curve. I just want to apply the force to check the displacement. so what should I do ? Do I need to load the force with time? Then plot force-deflection curve?
