|A simple phenomenological hypothesis of cumulative fatigue damage. Part I. Half-cycle formulation|
vol. 38 (2000), no. 2, pp. 96 - 106
A simple hypothesis of cumulative fatigue damage taking into account loading sequence effects is proposed for engineering purposes. Strictly phenomenological approach introducing notions of immediate and history damage factors is used to make the hypothesis simple, synthetic and having transparent and well analysable final mathematical expression. The hypothesis satisfactorily approximates constant amplitude fatigue lives and fatigue lives in H-L (high-low) and L-H (low-high) loading cases.
