heal.abstract	This paper presents an elastic-plastic finite element (FE) analysis of an axisymmetric circular cylinder with a circumferential notch subject to multiaxial nonproportional fatigue loading with variable amplitudes. The von Mises yield criterion and the linear kinematic hardening rule of Prager-Ziegler are applied to describe the elastic-plastic material behavior. Two different loading combinations are considered: (1) constant tension with variable amplitude torsion; (2) variable amplitude tension with variable amplitude torsion. Numerical results for the local stress-strain curves at the notch-root are presented and discussed. (C) 2002 Elsevier Science Ltd. All rights reserved.	en
