Effect of High Load on the Fatigue Behavior of Unnotched Graphite/Epoxy Laminates.

Abstract

The purpose of this research program is to verify experimentally the theoretical prediction for the effect of the high load on the fatigue behavior of unnotched composite laminates. A three-parameter fatigue and residual strength degradation model has been used to derive the number of load cycles a specimen can survive and the statistical distributions of the fatigue life and the residual strength after the specimen has survived an initial high load or periodic high loads. One set of the static ultimate strength data and one set of the fatigue scan data were generated to determine the three-parameter values appearing in the theoretical model.
