TWOSTAGE LOADING FATIGUE LIFE PREDICTION OF COMPOSITE LAMINATE

Abstract

Abstract:

This paper based on the data of twostage loading glass /epoxy composite laminate fatigue life experiment, integrates unlinear damage cumulative theory to get the residual life formula of the second loading, and then popularizes to get life formula of threestage and more stage. Compares the results get from the formula to the experiment, the result proves the formula is accurate. And so we can get the loading order effect on fatigue life of composite laminate.

Key words: composite laminate , twostage loading, fatigue life
