Abstract
Hill's 1948 anisotropic theory of plasticity is extended to include the con cept of isotropic-kinematic hardening. The "anomalous" effect can be accoun ted for by kinematic hardening. It is shown that the quadratic yield functi on can be used for sheet metals irrespective of its plastic strain ratio R. It is further shown that effects of thickness reduction due to further rol ling may be accounted for by kinematic hardening. (C) 1999 Elsevier Science Ltd. All rights reserved.
