Abstract
Uniaxial tension test and Brazilian (splitting tension) test were carried out on Inada granite in R, G and H directions, i.e., the directions perpendicular to rift, grain and hardway planes respectively. Comparison of the tensile strengths obtained by the tests showed that the strength by the Brazilian test was slightly higher than that by the uniaxial tension test. The difference between them, however, was small and less than standard deviation of the strength by the Brazilian test. Additionally, scatter of the strength by the Brazilian test was more than that by the uniaxial tension test. Regarding to anisotropy of Inada granite, it was recognized according to the results of both tests that the tensile strength in R direction was obviously lower than those in the other two directions.
