Abstract
The two-dimensional mesoscopic simulation method previously proposed by one of the authors for brittle microcracking solids is applied to the analysis of two-phase materials containing short fibers. Numerical results are presented to demonstrate validity of the proposed method. The effect of elastic property, slenderness, volume fraction, fiber-end cracks and orientation-distribution function of short fibers on overall elastic properties of two-phase materials has been studied. The microcracking behavior under tensile, shear and bending stress conditions accompanied by crack deflection, crack bridging and fiber pull-out has also been analyzed by the proposed mesoscopic simulation method.
