Abstract

The blades of high-temperature gas turbines working in conditions of prolonged loading nonuniform temperature field and the external forces. The properties of alloys of the blades are changing over time due to the phenomenon of creep. A method of determining equations coefficients for calculating the stress-strain state kinetics of turbine blades using the finite element of ANSYS on the example of a modern blade alloys is provided.
