RESIDUAL STRESSES IN THERMALLY LOADED SHRINK FITS

Abstract

This paper presents the results of comparative calculations by the finite element method of shrink fits having simple geometry on examination of the following aspects: yield criterion, hardening rule. temperature-dependence of the material parameters and the type of the uniaxial stress-strain curve. The necessary reference results for the comparison have been obtained by using partly analytical methods published by the author and others, partly the general purpose commercial finite element code COSMOS. The most significant difference has been detected at temperature-dependent material parameters.
