MODEL OF NONLINEAR ELASTIC-PLASTIC MATERIAL
Abstract
Within the concept of yield surfaces based on the principle of preserving the potential nature of elastic deformation the model of material is proposed. The active elastoplasticity process is presented by the alternation of plastic and elastic states. Deviatory cross sections of the yield surface are defined. Defining relationships are formulated. The model examples for orthotropic materialare considered.
