抄録: Two main shortcomings of the simple constitutive equations, which were proposed by the authors, were tried to revise. One is that the predicted failure envelope is straight. The confining pressure dependencies of the constants in the equations were investigated on the data obtained for Kamisunagawa sandstone and Indiana limestone. It was clarified that the constant B increases with confining pressure for the both rocks. Another is that the stress drop in the post-failure region is rather small. A simple elastic block model was examined in order to introduce larger stress drop.
