On the modeling of the shrink fit technology

We solve a one-dimensional problem of the theory of thermal stresses that models shrink fit on a cylindrical shaft. A distinctive feature in the statement is the account taken of the emerging and developing a plastic flow of the material of the assembly elements because of the nonstationarity of the temperature field and the dependence of the yield strength of the material on temperature. It is shown that irreversible deformation can significantly reduce the level of the final residual stresses providing the desired tightness.
