User-defined mechanical material behavior

If you use a hybrid element with user subroutine UMAT, by default Abaqus/Standard replaces the pressure stress calculated from the stress tensor returned by the user subroutine with that derived from the Lagrange multiplier and modifies the Jacobian appropriately (Hybrid incompressible solid element formulation).This approach is suitable for material models that use an incremental formulation Using Virtual Testing for Characterization of Composite Using Virtual Testing for Characterization of Composite Materials; models are being developed to accurately model composite systems so they can be used in implicit and explicit finite element analysis.
