FE fatigue analysis of notched elastic-plastic shaft under multiaxial loading consisting of constant and cyclic components

摘要

This paper presents a finite element analysis for a notched shaft subjected to nonproportional synchronous multiaxial loading. A combined tension/torsion is considered. For simplicity, one loading component is kept constant while the other is cyclic. The von Mises (von Mises R. Ges. Wiss. Gottingen, math. Phys. K1 1913: 582-93) yield criterion in conjunction with the kinematic hardening Rule of Prager and Ziegler (Prager W. Proc. Inst. Mech. Engrs 1955; 169:41-57; Ziegler H. Quart. Apply. Math. 1959;17:55-60) is Applied to describe the elastic-plastic material behavior of the notched shaft.
