    stress-strain curves in nonlinear analysis

    Michael Chou
      i am trying to do nonlinear analysis in CWAP and the results keeps going linear.

      upon some research in solidworks on "how to input stress-strain" curves in cosmos, it says that i am to input in a "stretch ratio" rather than strain. could this be why cosmos is just rejecting my input?

      also, if the FEA analysis goes beyond my stress strain curve that I input, what happens? does it just extrapolate the curve?

      any help would be greatly appreciated
