... Abstract It is possible to obtain the information of the preferred orientation of microcracks in granite by the measurement of the P-wave velocity, because the value of P-wave velocity is directly related to the density of microcracks. Therefore, we can obtain the information of three...

... properties of rock. The mechanical properties investigated other than fracture toughness are uniaxial compressive strength, Young's modulus, Poisson's ratio and P-wave velocity. The experimental results indicate that Kimachi sandstone shows anisotropic properties of Young's modulus, tensile strength...

... ABSTRACT Some laboratory tests such as absorption, porosity, P-wave velocity and uniaxial compressive strength (UCS) were performed to examine the physical property changes of ilmenite by microorganism. Physical properteis was quantitavely compared according to culture period in the condition...
