摘要：
The paper considers a procedure for the determination of the parameters of a limit state model for structural materials using a transcendental power function. The model is used to construct limiting stress amplitude diagrams for asymmetric high-cycle loading. The procedure has been tested by comparing the values of limit state model parameters obtained as a result of the basic experiment in pulsating loading cycle with the values calculated by the method of minimization of the sum-of-squares functional of deviations of experimental diagrams from calculated ones.
