A Constutitutive Model for Structured Clays. Modified Structured Cam Clay (MSCC) Model: Formulation, Verification and Implementation

      Аннотация: This book consists of six chapters and highlights of each chapter are presented as follows: • Chapter II presents the review of previous research on the constitutive modelling for structured clay. Topic discussion includes: the basis critical state soil mechanics and the model of Cam Clay family, framework for modelling the bonding materials, recent models developed for structured clay, theory for modelling soil in overconsolidated state, and the framework of the SCC model. • Chapter III presents the formulation of the MSCC model in conventional triaxial space. The elastoplastic formulation with considering the effect of soil structure is presented. • Chapter IV presents an extended version of the MSCC model for overconsolidated structured clay. The MSCC model is adopted together with the bounding surface plasticity formulation. • Chapter V presents the application of the MSCC model formulated in the generalised stress space. The finite element implementation of the MSCC model is presented and also coded in the generised finite element program, ABAQUS. • The list of input parameters and the source code of the model developed in this book are summarised in the appendices.
