The two-dimensional mesoscale simulation method using the natural element method previously proposed by the authors for brittle microcracking solids is extended to include the effects of microinclusions or microvoids. The mechanical effect of microinclusions or microvoids is considered by controlling the material constants in the neighborhood of these defects. The relationship between overall elastic moduli and area fraction of microinclusions or microvoids is studied. Considering regularly perforated sheets with holes as a 2-d solid containing microvoids, the relationship between macroscopic yield stress and distribution of microvoids is investigated to verify the validity of the proposed method.
