The detailed experimental procedures used to make measurements are to great extent standard methods when determining mechanical properties and deformation fields at high pressure. geological material tsembelis gauge Rosenberg Reservoir Characterization experiment hel longitudinal stress marble...

..., a methodology has been developed to examine, using a variety of time resolved and post experimental diagnostics, the fragmentation of small geological samples under explosive loading. Results from a variety of experiments will be presented, along with a discussion of future directions and challenges...

... are relatively large in the direction of 45 degrees to the horizontal direction. When there is only one crack, the moment of the lining is reduced near the crack. When there are more cracks in the lining, the bending moment has stress concentration near the crack. The conclusion of these experiments can provide...

... as the damage threshold was reached. Young et al. (2013) describe the RFDF facility used here and the experimental procedure for testing anisotropic gneiss is the same as that described in Nasseri et al. (2016). Table 1.

.... In order to investigate fracture behaviour of sandy mudstone subjected to dynamic loading, both experiments and numerical simulations are performed at different impact velocities, respectively. Experiments are carried out with the Split Hopkinson Pressure Bar (SHPB), and numerical simulation is conducted...

... ABSTRACT: The gradual transition from stick-slip to stable sliding is studied in lab experiments. The results allow concluding, that the sliding mode and the part of deformation energy spent to the seismic radiation are determined by a ratio of two parameters—the fault stiffness...

... ABSTRACT: Rock dynamics attracts great attention in rock mechanics. However, specimen preparation in experimental study is not easy. 3D printing started to be involved to improve this process, Including Polylactic Acid (PLA) and resin. However, their plastic behavior is much unlike brittle...

... ABSTRACT: This work is devoted to the investigation of spatio-temporal strain localizations under uniaxial quasistatic compression and tension of rocks with the use of the digital image correlation method. Conducted experiments allow us to establish specific forms of strain localization under...
