Loading-Rate Dependence of Rocks in Postfailure Region under Triaxial Compression

Table 1

Physicomechanical properties of the specimens.

Rock	Density (g/cm^3)	Saturated water content	UCS (MPa)	E (GPa)
Tage tuff	1.74	15.04%	22.26	3.83	0.32
Ogino tuff	1.81	10.53%	27.35	4.02	0.31
Emochi andesite	2.11	6.98%	77.50	10.05	0.25
Jingkou sandstone	2.29	4.81%	67.49	11.89	0.24

UCS: uniaxial compression strength, E: Young’s modulus, : Poisson’s ratio.
