Abstract

A simple model which is able to account for the distribution of matrix crack spacings as a function of applied stress in unidirectional fiber-reinforced brittle materials has been used to generate stress-strain curves for such materials up to the maximum stress level at which transverse matrix cracking can occur when a tensile stress is applied parallel to the length of the fibers. The results give an insight into how to tackle the experimental problem of determining accurately the level of first-matrix-cracking stress in such materials.
