Hello Everyone,

We have performed an uniaxial compression test of some stacks and got a stress- strain J curve as shown in image.

I am trying to utilize this curve as my material input and mostly tried everything feasible starting from plastic model to Hyperelastic models but simulation shows a huge margin as compared to test results. Only Marlow material model shows the promising results, but it doesn't converge fully.

Appreciate any suggestions !
