HARDENING EFFECTS ON THE STRESS DISTRIBUTION IN A SHRINK FIT UNDER CYCLIC THERMAL LOADING

Abstract

The variation of the stress distribution during the thermoelastic-plastic deformation in an assembled shrink fit due to a steady-state, homogeneous temperature cycle is studied. The use of the Tresca yield condition and its associated flow rule with a linear isotropic hardening rule makes a semi-analytical presentation possible. Numerical results are shown and compared with those of a non-hardening model.
