Dissipation function and yield condition for modelling plasticity of incompressible metals
Abstract
Dissipation function for use in modeling of plastic properties of incompressible metals is proposed in this paper. The dissipation function is dependent on the twoinvariants of plastic strain rate tensor and material parameters. Constant dissipation surface have three axes of symmetry in the deviatoric plane and the shape of deviatoric cross-section can change from the equilateral triangle to circle. The dissipation function is used for deriving the constitutive relation and the yieldcondition for perfectly plastic material. All equations describing the model are given in closed analytical form. Deviatoric cross-sections of the failure surface canchange from the equilateral triangle to circle. Material parameters are calibrated using typical strength tests.
