Hi,
I want to use USDFLD subroutine in my model. I want to use maximum principal plastic strain(MAX.principal) with respect friction angle.
how i call MAX.principal?
Another question which i have is about maximum magnitude between PE11 and PE22. If i want to maximum plastic strain between PE11 and PE22, should i writle my code like below? i want to use max plastic strain between PE11 and PE22 in each integration point. In the other words, if in my model in each integration point, plastic strain reach the valu that i defiend in field(1), then use friction angle. like belwo picture.
if i want to use cylindrical cordinate in my code, how can do it?
