VUMAT of a Generalized Standard Continuum Damage Model
13 Apr 2018 | Downloads | Contributor(s):: Zhenyuan Gao, Liang Zhang, Wenbin Yu
Based on a recently developed generalized standard continuum damage model (CDM), this VUMAT user subroutine provides a rigorous and robust framework for implementing various damage behavior into 2D or 3D solid elements in a finite element analysis (FEA). It is designed to be used with...
