Acoustic Emission Behavior of Rock-Like Material Containing Two Flaws in the Process of Deformation Failure

Table 1

The physicomechanical parameters of intact samples.

(MPa)	(MPa)	(GPa)		(°)	(g/cm^3)	P-wave velocity (m/s)	S-wave velocity (m/s)
5.45	0.90	1.30	2.44	9.03	0.84	3123	2657

Note: = uniaxial compressive strength, = tensile strength, = internal friction angle, = cohesive force, and = density.
