Implicit constitutive solution scheme for Mohr-Coulomb plasticity
Original language description
This contribution summarizes an implicit constitutive solutionnscheme of the elastoplastic problem containing the Mohr-Coulomb yield cri-nterion, a nonassociative now rule, and a nonlinear isotropic hardening. Thenpresented scheme builds upon the subdifferential formulation of the now rulenleading to several improvements. Mainly, it is possible to detect a positionnof the unknown stress tensor on the Mohr-Coulomb pyramid without blindnguesswork. Further, a simplifed construction of the consistent tangent opera-ntor is introduced. The presented results are important for an efficient solutionnof incremental boundary value elastoplastic problems.
