Submitted by prathyush963 on Mon, 08/26/2013 - 22:24 Hello, I am trying to input random strength (following weibull distribution) at each integration point. I want to use either USDFLD (preferably) or UMAT subroutines in Abaqus. Please help me in this regards. Any references/suggestions will be great. Log in or register to post comments2569 views
