title = "Variability of mechanical properties of bimrock",
abstract = "This paper used PFC2D to simulate bimrock mechanical behaviors under uniaxial compressive tests and presents the means and variances of uniaxial compressive strength (UCS), Young's modulus (E), and Poisson's ratios (o) for various volume fractions and strain gauge lengths. The results show that UCS, E, and v increase as Vf increases, and simulated E and ν were consistent with the differential scheme and Hashin-Shtrikman bounds. In quantifying the uncertainty of Young's modulus and Poisson's ratio measurements using a strain gauge, the measurement uncertainties initially increase and then decrease with increasing Vf, when Vf =0.3∼0.4 (0 or 1), Young's modulus and Poisson's ratio reach a maximum (minimum) value. In addition, crack propagation was also observed and discussed in this paper.",
