Methodology of strength calculation under alternating stresses using the diagram of limiting amplitudes

Abstract

The work proposes the algorithm to calculate strength under alternating stresses using the developed methodology of building the diagram of limiting stresses. The overall safety factor is defined by the suggested formula. Strength calculations of components working under alternating stresses in the great majority of cases are conducted as the checking ones. It is primarily explained by the fact that the overall fatigue strength reduction factor can only be chosen approximately during the component design as the engineer at this stage of work has just the approximate idea on the component size and shape.
