Web1 ian. 1993 · A new method is proposed for multiaxial fatigue life prediction using correlation parameters based on virtual strain energy as a measure of fatigue damage on critical planes of fracture. The virtual strain-energy parameters are physically associated with two different modes of fatigue fracture planes. WebWhen the varying loading is random it is difficult to estimate the fatigue life. The rainflow counting algorithm (also known as the “rainflow counting method”) is used in the analysis of fatigue data in order to reduce a spectrum of varying stresses (strains) into a set of simple stress (strain) reversals. Its importance is that it allows ...
