Axisymmetric Problem of Thermoplasticity for a Piecewise Homogeneous Ring

详细

We develop an analytic approach to the determination and analysis of axisymmetric thermoplastic states in piecewise homogeneous rings subjected to nonstationary heating. The numerical analyses of the thermoplastic states of two- and three-layer annular plates are performed. An example of the problem of determination of compressive residual stresses in a plate subjected to local heating by a normal circular heat source illustrates the efficiency of the proposed approach in the case where the yield strength is a function of temperature.
