Deviatoric section shape functions for materials exhibiting dependence on shear-to-axial yield stress ratio
Proposal of a class of smooth functions describing shape of the deviatoric section of the failure surface of isotropic materials is given. Their convexity is investigated and the resultant restrictions to the free parameters are derived. Applications to pressure sensitive or insensitive materials as...
