摘要

We study the thermoplastic state of plates subjected to the action of localized heat sources with arbitrary distribution profiles. For the investigation of plastic deformations considered within the framework of the theory of nonisothermal yield associated with the von Mises yield condition, we develop a numerical algorithm based on the use of the boundary element method. We also consider the problem of choosing the modes of heating aimed at reducing residual stresses by using either moving or immobile heat sources whose intensity is described by the Gaussian normal-circular law.
