Authors: AHMET N. ERASLAN, YUSUF ORÇAN

Abstract: This article presents a comprehensive parametric analysis of rotating variable thickness elastoplastic annular disks with inner boundaries subject to pressure or mounted on rigid inclusion. A computer model based on von Mises yield criterion, J_{2} - deformation theory and nonlinear isotropic hardening is developed. Elastic limit angular velocities, partially plastic deformations and plastic limit angular velocities are investigated with emphasis on the determination of the effects of all the geometric, material and hardening parameters involved.

Keywords: Stress analysis, Elastoplasticity, Variable thickness, Von Mises criterion, Nonlinear strain hardening
