The brittleness of rock
0 ◆ 2 (b) Figure 9 Simulation of the brittleness index Fig. 9Brittlenessindicesofsimulationcomputation corresponding to Figure 8 (a),[link widoczny dla zalogowanych], Figure 9 (b) corresponds to the Figure 8 (b). Shows this model can simulate brittleness index increases with the confining pressure, decreasing phenomenon. 5 Conclusion (1) a brittle deformation characteristics of both is a kind of material properties,[link widoczny dla zalogowanych], brittle fracture can be cemented, said rod element. Rock brittleness concept is not uniform. (2) summarizes the brittleness index of commonly used measure, and then proposed a brittleness index and verify its applicability: With the increase of confining pressure decreased brittleness index,[link widoczny dla zalogowanych], brittleness decreases. (3) Binary medium model for geotechnical materials can be loaded during the stress-strain characteristics of good simulation results show that this model can simulate the strain softening of low confining pressure to the high confining pressure the strain hardening ,[link widoczny dla zalogowanych], and the brittleness index increases with the confining pressure decreases.
