Microstructural Imaging of Shock-Recovered Berea Sandstone and Quartz Sand Using Scanning Electron Microscopy

PDF Version Also Available for Download.

Description

A number of shock-recovery experiments have been performed on Berea sandstone for different conditions: dry, water-saturated, hydrostatically water-pressurized and Helium gas-pressurized. The authors also conducted experiments with purified quartz sand in dry and water-saturated conditions with a grain size between 212 to 250 {micro}m and 250 to 300 {micro}m to compare with damaged Berea sandstone. The shock stresses in the range between 1.2 to 9.8 GPa were achieved by impacting projectiles accelerated by a single-stage light-gas gun. Different flyer plate thicknesses were used to produce different shock pulse durations. The water-pressurized sandstone targets were hydrostatically pressurized between 7.58-7.79 MPa, whereas ... continued below

Description

A number of shock-recovery experiments have been performed on Berea sandstone for different conditions: dry, water-saturated, hydrostatically water-pressurized and Helium gas-pressurized. The authors also conducted experiments with purified quartz sand in dry and water-saturated conditions with a grain size between 212 to 250 {micro}m and 250 to 300 {micro}m to compare with damaged Berea sandstone. The shock stresses in the range between 1.2 to 9.8 GPa were achieved by impacting projectiles accelerated by a single-stage light-gas gun. Different flyer plate thicknesses were used to produce different shock pulse durations. The water-pressurized sandstone targets were hydrostatically pressurized between 7.58-7.79 MPa, whereas the gas-pressure samples were pressurized to 27.5 MPa using helium gas. The microstructural damage of all specimens is being investigated by using scanning electron microscopy (SEM) in order to determine differences for these conditions. In this report they will present the results of the systematic SEM investigations for each experiment. The scientific results and discussions including X-ray computed micro tomography and statistical analysis are presented elsewhere. Overall, they collected around 1600 SEM pictures, which are available in electronic form on Compact Disks (CDs). They also provide the results of the laser particle analysis on the CDs.
