A research note on certain loading directions in rate independent plasticity Academic Article

abstract

• Starting with the strain space formulation of rate independent elastic-plastic materials, the notion of `work-instability', i.e. the possibility of an elastic plastic material undergoing spontaneous plastic deformation in a workless manner, is discussed. Some simple criteria for a material to be work stable are presented. An example of a material that satisfies Prandtl-Reuss type equations with strain softening is presented and it is demonstrated that for plane homogeneous deformations, the material shows the possibility of spontaneous plastic flow even if the in-plane strains are held fixed, if it softens beyond a critical amount.
