INVESTIGATION OF THERMAL STRESSES IN A MONOBLOCK STOPPER AT DIFFERENT VALUES OF THE LINEAR EXPANSION COEFFICIENT

An algorithm for investigation of the dynamics of temperature fi elds and thermal stresses in bodies of intricate geometric shape has been developed on the basis of the fi nite-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 coeffi cient. The maximum value of the linear expansion coeffi cient whose excess terminates in the failure of the monoblock stopper has been determined under specifi ed heat-transfer conditions.
