— Structural element service conditions often involve a number of thermo‐mechanical loading factors. Increasing the number of these variable factors, the evaluation of crack growth resistance becomes rather complicated. So, it is of practical importance to predict the material crack growth resistance over a wide range of service conditions from the results of a limited number of standard specimen tests under specified loading conditions. The present note is based on a mathematical theory and tests on a limited number of standard specimens. A functional dependence has been obtained between the crack growth rate and kinetic equation parameters and the values of thermo‐mechanical loading factors.
