摘要：

An algorithm for investigation of the dynamics of temperature fields and thermal stresses in bodies of intricate geometric shape has been developed on the basis of the finite-element method. With the example of a monoblock stopper; the authors have modeled the process of heat transfer and the dynamics of thermal stresses, and also studied thermal stresses at different values of the linear expansion coefficient. The maximum value of the linear expansion coefficient whose excess terminates in the failure of the monoblock stopper has been determined under specified heat-transfer conditions.
