The tensile strength of composite plates with unidirectional cords depends on the way the load is distributed within the matrix by the cords. Of particular interest is the effect of a broken edge cord or a number of in-line fractured edge cords on the breaking strength of the plate when it is subjected to axial loading. This paper describes a model for estimating the maximum allowable number of broken tensile members in a bonded composite plate before catastrophic failure occurs. The model has application to the analysis of steel-cord and Kevlar-cord elastomer belts containing broken edge cords as the result of impact damage.
