Abstract

The analysis of distribution of temperatures and stresses in the elements of constructions subjected to heavily harmonic thermal actions is conducted. The similar action is tested by the elements of constructions, for example, at the technological process of application of hard-alloy coatings by plasma spray. Because of simplified analytical models and with the help of finite element method for the elements of constructions the rational conditions of the technological process are defined, at which the maximum temperatures do not exceed admissible values and the inelastic strains do not appeared.
