Abstract

Investigations were carried out into the dependence of the accuracy of estimates of the distribution parameters of the endurance limit on methodological special features of carrying out fatigue tests by the method of stepped load variation. The effect of the number of specimens, the increase of the load levels, and also of the sequence of testing the specimens on the accuracy of estimates of the examined parameters is shown. Recommendations are made for determining the basic estimates of the distribution parameters of the endurance limits by the method of stepped load variation.
