The disturbed state concept (DSC) is a relatively new development and until now has lacked extensive attention in a publication. This book presents the first detailed, theoretical treatment of the DSC and shows that it can provide a unified and simplified approach for mathematical characterization of the mechanical response of materials and interfaces. The author compares the DSC with other available models, identifies the physical meaning of the relevant parameters, validates the DSC models implements the model in computer procedures, and validates those procedures by comparing predictions with observations.
Zusammenfassung
The disturbed state concept (DSC) is a unified, constitutive modelling approach for engineering materials that allows for elastic, plastic, and creep strains, microcracking and fracturing, stiffening or healing, all within a single, hierarchical framework. Its capabilities go well beyond other available material models yet lead to significant simpl
