Damage Constitutive Model of Microcrack Rock under Tension

Table 1

Mechanical parameters of the rock samples.

Rock samples	ρ (g/cm^3)	E (GPa)	fc (MPa)	ν	φ (°)
	2.90	13.44	123.9	0.25	60.80

ρ refers to the density, E refers to the modulus of elasticity, f_c refers to the uniaxial compressive strength, ν refers to the Poisson ratio, and φ refers to the internal friction angle.
