GENERALIZED PLASTICITY AND SOME MODELS FOR GEOMECHANICS

Abstract

Abstract: In this brief note, we have (a) introduced a very general form of plasticity definition; (b) indicated several types of models used for monotonic and transient loading of soil-like materials, which do not depend on time effects. The details of each form are given elsewhere but we believe that the new framework provides an easier and more general interpretation of a variety of behaviour form.

Key words: soil erosion, critical slope gradient, flow scouring capability, soil stability
