Abstract
Using the linear hypothesis of fatigue damage accumulation, the values of breaking tensions are calculated when simulating fatigue resistance tests of machine parts with a linearly increasing load. The calculations were carried out for the range of discrete values of the endurance limit in the range of 100-500 MPa and the rates of increase in the stress range 100-500 Pa/cycle. The calculation showed that the error of the breaking tensions depends on the rate of increase in the load and, in the limiting case, does not exceed 15 %.
