Shock wave loading
WebTo clarify damage or degradation mechanisms of underground shock disturbance of deep caverns, a customized model of a deep cavern to subjected ground shock was employed to simulate the following properties and processes: crustal stress loading, cavern excavation, and ground-shock disturbance loading. The similar model specimen was a cube of … Web25 Jul 2002 · Therefore we also synthesized pure coesite samples for shock wave loading with a cubic multi-anvil device at approximately 4 GPa and 900°C. The final bulk density (ρ 0) of these samples is 2.92 ± 0.03 g/cm 3. The synthesized coesite and stishovite samples are sectioned into disks of ∼1 mm thickness and polished for shock wave experiments.
