Abstract

The Ziegler modification of the Prager hardening rule has been used in conjunction with a combined isotropic–kinematic workhardening rule in order to predict the Bauschinger effect during cyclic loadings. There has been some controversy as to whether the above workhardening rule predicts a stress increment which is consistent with the yield condition. The purpose of this communication is to establish the combined hardening rule as a consistent statement in order to clarify its correctness.
