Calculation of fatigue damage under cyclic complex loading considering the effect of the strain rate
https://doi.org/10.22349/1994-6716-2023-114-2-136-146
Abstract
A method has been proposed for calculating fatigue damage under cyclic loading, in which the loading in half-cycles is not simple, i.e., the stress components in a half-cycle do not change proportionally to one parameter. In addition, the proposed method takes into account the situation when the strain rate in a half-cycle affects the degree of damage to the material (for example, in the case of material deformation under conditions of creep or exposure to a corrosive environment) and this rate can change in different loading half-cycles.
