Products: Abaqus/Standard Abaqus/Explicit Abaqus/CAE
Benefits: You can now limit the load carrying capacity in tension when the Mohr-Coulomb criterion is used in Abaqus. This is useful in geotechnical applications for failure and strength predictions, when material has limited strength in tension.
Description: Abaqus now gives you the option to include tension cutoff along with Mohr-Coulomb plasticity when modeling geological materials. Tension cutoff is modeled using the Rankine surface, and you can provide either hardening or softening of the failure surface in tension. A smooth non-associative flow potential that closely follows the Rankine surface is used to model plastic flow on the tensile failure surface.
