Journal of MMIJ. 124:7-19
Compressive fracture process of rock under the uni-axial compression is discussed, as a result of the sub-critical crack growth in it. A numerical procedure for the failure prediction is presented and discussed, basing upon the critical pressure-crac

Analysis of the pure mode I crack propagation (KII = 0) from tips of compressible joints in rock is improved by a minute computation of internal stresses in the joints, which takes a compressibility of joint and a dilatational overall sliding on join

The rock mass properties such as deformability and strength are highly dependent on the existence of cracks. The crack propagation directly influences the decrease of effective Young's modulus and rock mass failure, and the analysis of crack propagat
