Cracking Resistance of Short-Fiber-Reinforced Composites
A crack bridged by discrete fibers in an infinite medium is modeled. A crack model is developed to consider nonlinearities in the fiber stress–displacement relation independently of the actual physical processes governing this relation. The effects of fiber size and placement on the intensity of crack tip stress are considered. As an example, a crack in a short-steel-fiber-reinforced concrete matrix composite is considered. Variations in the intensity of crack tip stress due to fiber debonding, pullout, and associated stress discontinuities are considered.
