Has anyone used Crushable foam model in CalculiX? (Also called as Deshpande Fleck model)
I found that CalculiX does not have this material model inbuilt in it like ABAQUS.
I plan to write a UMAT for it and implement it in CalculiX.
Any suggestions on how to start?
I am not looking for the complete UMAT code itself, rather I’d like to discuss/get help on how to write it from scratch.
