Calculation of the parameters of local heating of plates to induce residual compressive stresses in specified regions

On the basis of the solution of the problem of thermoplasticity the article suggests an algorithm for selecting the parameters of local heating of plates so as to induce residual compressive stresses in specified regions in which failure may set in. The physical equations that are used are the relations of the nonisothermal theory of flow associated with Mises ' condition of yield. The solution is constructed with the methods of integral equations and successive loadings, and the parameter of loading is time. The authors investigate the influence of the disposition of the heat sources relative to regions of reduced strength on the magnitude and nature of the distribution of residual compressive stresses.
