Abstract
Achieved theoretical substantiation of reliability stress in the cross section of the sample values for fatigue tests performed and their experimental confirmation. It is found that the test circuit for the received torsional bending with an increase in applied load on the sample type II cross-section of 7.4 mm by 1 H-level voltage value in the sample section increases by 2.52 MPa. A dependence to predict the stress level in the low-cycle and the cycle region in the cross section of the sample with increasing load.
