Beschreibung:
This book presents the basic theories of Plastic Mechanics of Geomaterial, including the static and dynamic mechanical properties, nonlinear and classical plastic theory, yield surface theory, hardening model, flow rule and loading-unloading criterion, the calculation theory of principal stress axe rotation, and limit analysis of geomaterial and the latest advances in FEM limit analysis. It also set forth the typical static and dynamic constitutive model of geomaterial in detail.
Introduction.- Stress and strain and its basic equations.- The basic mechanical characteristics of the geomaterial.- The elastic model of geomaterial.- Classical Plasticity Theory.- The development of the plastic theory of geomaterial.- The static elastoplastic model for geomaterial.- Generalized plastic mechanics considering the rotation of principal axis of stress.- The dynamic constitutive model of geomaterial .- Limit analysis for geotechnical engineering.
