Input stress-strain values for nonlinear elastic material in Event Simulation.

Input stress-strain values for nonlinear elastic material in Event Simulation.

I had created a custom materal (saved into Favourites Library) called "Polycarbonate - nonlinear elastic" by typing these strain-strain value pairs in both the tensile quadrant and compressive quadrant (see attachment):

Strain     Stress (Mpa)

0.0          0.0

0.01        22.75

0.02        37.0

0.03        49.0

0.04        56.0

0.05        60.0

0.06        61.5

0.07        62.01

The Nonlinear Static Stress study ran successfully with "Polycarbonate - nonlinear elastic" and produced results I expected.

But Event Simulation study would not run with that "Polycarbonate - nonlinear elastic" material. Please have Event Simulation run with "Polycarbonate - nonlinear elastic" material, and other materials that do not have a linear stress-strain relationship between zero and Yield Strength.

There are many studies requiring contacts (of Event Simulation) of nonlinear elastic materials.

Thank you.
