OS4-3-1 Fatigue Life Prediction of CFRP Laminates Under Variable Stress Amplitude, Frequency and Temperature

Abstract

This paper is concerned with the applicability of statistical linear cumulative damage (SLCD) rule for predicting the fatigue life under variable cyclic loading for CFRP laminates. The three-point bending fatigue tests for plain-woven CFRP laminate were carried out under various cyclic loadings with constant and variable load amplitude, load frequency and temperature. As results, the applicability of SLCD rule to the flexural fatigue life of this CFRP laminate was confirmed for the cases of variable load frequency and temperature as well as variable load amplitude from the viewpoint of statistics.
