摘要：

The authors have re-examined the Strength-Life Equal Rank Assumption (SLERA) that is used in the fatigue life prediction of composite materials, and suggest that this assumption may be valid for a wide range of fibre-reinforced epoxy laminates subjected to tensile, compressive or shear fatigue loadings. The evidence presented here suggests that there may be an exact correlation between the initial static strength and fatigue life expectancy. A corollary is that scatter in the fatigue data is a consequence of the variation in the static strengths of individual specimens. Using SLERA, an efficient and usable life predictive technique has been developed for fibre-reinforced composite materials.
