... Natural fractures are widespread in rock. Fracture development depends on a wide range of factors such as burial history, temperature, strain rate, mechanical properties, layer geometry, and chemical reactions. We developed a three-dimensional (3D) simulator that couples tectonic strain...

... scales to sub-millimeter crystallographic scales. It is generally agreed that fractures originate at lattice imperfections. Mechanism of their propagation however remains poorly understood and speculatively depends on a combination of factors including material heterogeneity, internal grain arrangements...

... equations We applied the HPM-SP to the failure simulation of rock masses including complex free surfaces. We briefly explain the basic concept of the method and introduce the outline of failure analysis based on the damage mechanics with a statistical approach. In the HPM-SP, the strain tensor components...

... to the mechanical limitations of the pump, cycle frequency can not exceed 1 Hz. For higher frequencies, use of mechanical actuator must be developed. Figure 1 summarizes the laboratory setup. Figure 1: Schematic of the pressure pulsing apparatus After the experimental setup was calibrated, we performed a benchtop...
