Certification of Composite Aircraft Structures Under Impact, Fatigue and Environmental Conditions. Part 2-Scale Effect in Fatigue of Composite Materials.

Abstract

The effect of size on the endurance limit of composite materials has been found to depend on the statistical scatter. For structures that can be considered as composed of a number of basic elements arranged in series, the fatigue life of the structure can be predicted if the distribution of the basic element is known. This prediction technique has been verified for graphite/epoxy structures constructed from three basic elements with central hole arranged in series and subjected to a compression loading.
