KINEMATIC HARDENING RULES IN FINITE PLASTICITY .2. SOME EXAMPLES

We consider finite plasticity laws which are represented by means of d ual variables and satisfy the intrinsic dissipation inequality. Within two families of dual variables, two different formulations for a kine matic hardening rule, referred to as Model 1 and Model 2, are proposed . In order to discuss basic properties of the two models, the predicte d response for some simple deformations is calculated. It turns out th at e.g. with respect to the simple shear and simple torsion the two mo dels differ mainly in the effects of second order.
