There are a wide variety of short fiber reinforced cement composites, such as strain hardening and multiple fine cracking in tension. Quantitative material design methods considering the properties of ma- trix, fiber and their interface should be established. This paper introduces numerical model by means of three- dimensional meso-scale analysis (i.e. matrix, fiber and their interface are discretized respectively.), to simu- late the tensile fracture including strain hardening and multiple fine cracking. The fibers with specific length and diameter have been arranged within the specimen, and loading tests in analysis have been also carried out to compare with experimental results. It was clarified that the proposed model can be roughly simulated the tensile failure of high strength Strain Hardening Cementitious Composites (SHCC) includes crack patterns. And the effects of matrix strength, its variation and fiber distribution on the tensile fracture were numerically investigated.
