Finite deformation of particulate geomaterials: frictional and anisotropic Critical State elasto-plasticity
… tangent. A framework for the analysis of anisotropic finite deformation elasto-plasticity is presented and a full incremental finite-element formulation provided. The first constitutive model developed in this thesis is a non-associated frictional perfect plasticity model based on a …

Experimental investigation and constitutive modeling of the large deformation behavior of anisotropic steel sheets undergoing strain-induced phase transformation
… which describes the martensite content as a function of plastic strain, the stress triaxiality, and the Lode angle parameter. Furthermore, a phenomenological plasticity model is developed comprising an anisotropic yield function, an isotropic hardening law, and a nonlinear kinematic hardening …
