WebAbout this book. Generalized Plasticity deals with the plasticity of materials and structures. It is an expansion of the "Unified Strength Theory to Plasticity Theory", leading to a unified treatment of metal plasticity and plasticity of geomaterials, generally. WebIn contrast to the classical elastoplastic model, the generalized plasticity model by Pastor et al. [ 17 ], referred to in the following as the PZC model, has neither an explicitly defined yield surface nor a plastic potential surface and does not need a consistency law to determine the plastic modulus.
