Eccentric Shear-Lag Model and Implications on the Strength of Fibrous composites

摘要

The stress field in the vicinity of a broken fiber-reinforced composite isanalyzed by means of a shear-lag model. The broken filament is positioned eccentrically relative to its neighboring fibers to simulate the commonplace non-uniformity of fiber spacing within the transverse plane. It is shown that a fiber break gives rise to severe bending, in addition to tension, in the neighboring
