Incorporation of an anisotropic (texture-based) strain-rate potential into three-dimensional finite element simulations

An anisotropic (texture-based) strain-rate potential is incorporated directly into a finite strain formulation in the form of an elastoplastic constitutive model. The technique is based on the Taylor theory of crystal plasticity and thus takes texture-induced variations in properties into account. A three-dimensional user material (UMAT) subroutine has been developed and implemented in the commercial finite element code ABAQUS. A stress …
