On the Experimental-Analytical Method of Appraising the Thermal Fatigue SStrength of Structural Components under Non-Steady Thermal Loading (Ob Eksperimentalno Analiticheskom Metode Otsenki Termoustalostnoi Prochnosti Elementov Konstruktsii pri Nestatsionarnom Teplovom Nagruzhenii),
Abstract
A method is proposed for the complex experimental-analytical investigation of thermal fatigue strength of structural components during non-steady thermal loading. The method is based on identifying the thermal fatigue sensitive regions in a structural component, selection of an appropriate model to represent these regions and the condition for its testing, and finally testing the model to failure to determine the original components' thermal fatigue life. In particular, the method is applied to the problem of thermal fatigue of gas turbine blades.
