Here we describe the use of the coupling between Code_Aster and the behavioral law integration module UMAT, a « user » routine whose arguments are specified by the Abaqus code.

Attention: the use of these laws of behavior « by custom » implies a specific validation for the study under consideration, because we are outside the field qualified of*Code_Aster*.
