Abstract

Fatigue crack growth rate data reduction is a challenge and it becomes hairy when a total life modeling is involved. This paper summarizes various methods, namely, secant, incremental polynomial and weighted moving average methods and introduces a less known but powerful method called locally weighted least square regression technique. The method was validated on metallic compact tension specimen and applied to mode II fatigue results of AS4/8552 composite laminate.
