  Hello ,
  
  I am trying to simulate nanocomposite tensile tests with symmetrical displacement, I did a static structural analysis but I manage to have the strain-stress curve with only the linear curve.
  
  What can I do in order to have both the linear and the non-linear curves?
  materials characteristics are complete.

  What is the material model that you have used? Can you share a snapshot of your material input from the Engineering Data?

  Hi
  I found it , one of the material characteristics was incorrect.
