Multi-mechanism Modeling of Inelastic Material Behavior

Multi–mechanism models describe the mechanical effects of metals, polymers, and geomaterials in addition to their function in developing constitutive equations. This text explains how multi–mechanism models represent monotonic and cyclic mechanical behaviors and deformation mechanisms with material parameters and internal variables.  With a phenomenological focus, the book thoroughly describes the principles of plasticity, damage, creep behavior, creep plasticity interaction, and cyclic responses under proportional and non–proportional loading paths for isotropic and anisotropic materials.  Various applications of the extensive experimental data qualify this book as a valued reference tool for students, material mechanics researchers, and mechanical engineers.
