Abstract

A computational model is developed to predict elastic and elastic-plastic stress distribution in a nonlinearly hardening cooling fin of variable thickness subject to centrifugal force. The model is based on a realistic conduction-convection mechanism, von Mises yield criterion, Henky's deformation theory and a Swift-type strain hardening law. Temperature dependency of modulus of elasticity, uniaxial yield limit, coefficient of thermal expansion, and thermal conductivity of the fin material is taken into account.
