Products: Abaqus/Explicit Abaqus/CAE
Benefits: The Mohr-Coulomb criterion, which is widely used in geotechnical applications for failure and strength predictions, is now available in Abaqus/Explicit.
Description: Abaqus/Explicit now provides the Mohr-Coulomb plasticity model that previously was available only in Abaqus/Standard. The constitutive model is an extension of the classical Mohr-Coulomb failure criterion. It is an elastoplastic model that uses a yield function of the Mohr-Coulomb form; this yield function includes isotropic cohesion hardening/softening. The model uses a flow potential that has a hyperbolic shape in the meridional stress plane and has no corners in the deviatoric stress space. This flow potential is then completely smooth and, therefore, provides a unique definition of the direction of plastic flow.
Import between Abaqus/Standard and Abaqus/Explicit is now supported for the Mohr-Coulomb plasticity model.
