Dear all,
I hope you are doing well! I am trying to simulate some 3D printing composite designs under impact loading conditions. The material I use is verowhite and tangoblack ( polymer resin with one is stiff and one is rubber-like soft). Some material model I have tried was plastic kinematic(MAT3), plasticity polymer((MAT89), and bergstrom boyce rubber(MAT269). Here is the result I have but I think there maybe a lot computation error as the elements act very weird. I wonder if anyone has any suggestions for me. Thank you!
