Generalized plastic ordinary state-based peridynamic model with shear deformation of geomaterials
This article aims to propose a generalized plastic model in the ordinary state-based peridynamic framework to study the elastoplastic behaviors of geomaterials, in which the constitutive relationship is obtained by the experimental data of the geomaterial. In the ordinary state-based peridynamic model for generalized plasticity, the non-associated flow rule is considered, where the yield surface does not coincide with the potential function. The formulations of the ordinary state-based peridynamic model for the non-associated plasticity are derived based on energy conservation. The iterative solving algorithm and numerical procedure of our model are proposed to simulate the deformation of geomaterials. Numerical examples of confined and conventional triaxial compression tests for Chongqing red clay are presented to illustrate the effectiveness and robustness of our model. The present numerical results are in good agreement with the experimental data when compared with the laboratory results reported in the literature.
