User-defined interfacial constitutive behavior

User-defined interfacial constitutive behavior:

  • is provided so that any constitutive behavior across an interface can be added to the library of existing models such as softened contact and Coulomb friction;

  • requires that a constitutive model (or a library of models) for the interface be programmed in user subroutine UINTER in Abaqus/Standard;

  • requires that a constitutive model (or a library of models) for the interface be programmed in user subroutine VUINTER in Abaqus/Explicit when using the contact pair algorithm;

  • requires that a constitutive model (or a library of models) for the interface be programmed in user subroutine VUINTERACTION in Abaqus/Explicit when using the general contact algorithm;

  • is available only for surface-based contact definition involved in stress/displacement, coupled temperature-displacement, coupled thermal-electrical-structural, or heat transfer analysis; and

  • requires considerable effort and expertise: the feature is very general and powerful, but it is intended for advanced users.
