Abstract: Abstract Stress-strength interference (SSI) analysis method has been applied to reliability estimation of a broad range of structural components under a variety of loading conditions. This method is successful for static strength failure. For fatigue failure, some of the current methods use SSI technique directly, assuming that the distributions of applied stress and fatigue strength corresponding to specific number of cycles to failure are known. However, the exact distribution of fatigue strength at specific number of cycles to failure cannot be obtained from a test. Alternatively, methods to determine fatigue strength distribution from fatigue life distribution were proposed.
