Reply To: Material Damge Model

[Sebak Oli]

Hi Hassan Jishi,

I have written a usermat for matrix and inclusions which also include damage. So at some displacement those material will lose all stiffness (Just like ekill, I guess) but when I combine them as a composite and apply displacement, I get element distortion issue. No matter what I do I am not getting softening curve for the composite in APDL. Let alone the softening curve, I can't even apply tiny displacement. I am not sure if I should perform analysis in LS-Dyna or there is a way to resolve the issue of distortion element. If you could provide anything related to APDL  or LS-Dyna or any other materials to study, it would be helpful. I really appreciate the suggestion.
