In this paper, the method of determination for anisotropy ratio of orthotropic brittle material in diametrical compression test is shown. For this method, strains are calculated on the direction of parallel and normal to compression at the center of cross section under several anisotropy ratios with theoretical solution. And the relationship between ratio of these strains and anisotropy ratio is shown by the graphical representation in this paper. Using this graphical representation, anisotropy ratio can be obtained with measuring strains occurred at center of cross section of specimen.
