Abstract

A solution is given of a one-dimensional problem of the theory of thermal stresses which simulates the hot shrink fit of a cylindrical clutch on a cylindrical shaft. The distinguished feature in the statement of the problem is taking into account the originating and developing plastic flow of the material of the assembly components due to the nonstationarity of the temperature field and the dependence of the yield material strength on the temperature. It is shown that irreversible deformation may significantly reduce the level of the final residual stresses providing the desired tightness.
