heal.abstract	An approximate model is presented for estimating elastic-plastic stresses and strains in a notched bar subjected to synchronous non-proportional tensile and torsional cyclic loading. To begin with, it is applied to a multiaxial synchronous proportional loading system. A detailed FE analysis is performed for an axisymmetric bar of circular cross-section with a circumferential notch. The accuracy of the proposed approximate model is first established. The elastic-plastic material property is described by the von Mises yield criterion and a linear kinematic hardening rule. The comparison of the FE results with those estimated by the proposed approximate model shows good agreement for all loading cases investigated. (C) 2003 Elsevier Science Ltd. All rights reserved.	en
