Abstract

We propose a procedure of numerical analysis of three-dimensional thermal stressed states of machine parts with multiplayer heat-shielding coatings based on the use of the SPACE finite-element software package. A detailed analysis of thermal and stressed states of wedge-shaped models simulating the blades of gas-turbine engines with coatings of different thickness subjected to thermal cycling is performed. The character of the influence of the thickness of coatings on thermal and stressed states in the half-cycles of heating and cooling is studied.
