A Generalized Cap Model for Geological Materials
Abstract
The full scope and theoretical basis of the cap model is described so as to demonstrate and define the capabilities and limitations of the model. A cap model falls within the framework of the classical incremental theory of plasticity and is based on a loading function which serves as both a yield surface and plastic potential. The model describes material behavior in compression and, in general, some type of tension behavior must be postulated for completeness. Tensile behavior will not be considered here. Particular forms of the cap model are adequate for many purposes, however, it is desirable to describe the model in its most general form so as to clearly indicate the adaptability and flexibility as well as the limits of the cap model approach. This has been done, and the procedure for fitting the cap model is briefly described.
