Modeling and Testing for Anisotropic Behavior of Soils

A rate‐independent elastoplasticity constitutive model is developed to account for various factors, such as friction, stress path and history, and induced and initial anisotropy in the response of geological materials. A hierarchical approach is adopted whereby models of progressively increased sophistication are developed from a basic isotropic hardening associative model, with the concepts of anisotropic hardening and nonassociativeness, and a...
