Granular flows are important in geophysics to the pyroclastic flow, debris flow, and avalanches. Understanding their complex and rich physics is therefore important in simulating their dynamics.
A method combining partial-volume and blurring effects can be used to measure small features in computed tomography data volumes.
Imaging crack propagation in shales using twin optical cameras and fast X-ray radiograph acquisition.
During triaxial compression experiments, acoustic monitoring reveals compaction localization in a high porosity limestone, accompanied by a significant decrease in P-wave velocity.
