| Abstract: | We have developed and implemented a method for calculating the fields of parameters of the crack-tip creep stress-strain state
by taking direct account of the higher-order terms. The paper presents some calculated data on the fields of crack-tip stresses,
creep strain rates, and amplitude ratios in the creep case. The influence of loading biaxiality on redistribution of stresses
between the creep stages and on the constraint parameters in failure is assessed.
