Abstract

In this work we employ x-ray tomography, 3D digital image analysis and 3D-volumetric digital image correlation techniques to characterize localized deformation phenomena in sandstone. The specimens considered have been deformed in triaxial compression under a range of confining pressures (20-190MPa). Shear or compaction bands were observed, at low and higher confinement respectively. X-ray tomography images have been acquired before and after loading (unconfined) at different spatial resolutions (30 and 90 µm voxel size). The combination of both x-ray tomography and 3D DIC provides insights into the geometry and mechanisms of the localized features.
