User subroutine to define the damage initiation criterion.

User subroutine UDMGINI:

  • can be used to specify a user-defined damage initiation criterion;

  • allows the specification of more than one failure mechanism in an element, with the most severe one governing the actual failure;

  • can be used in combination with several Abaqus built-in damage evolution models, with each model corresponding to a particular failure mechanism;

  • will be called at all integration points of elements for which the material definition contains user-defined damage initiation criterion;

  • can call utility routine GETVRM to access material point data; and

  • is currently available only for enriched elements.
