Full-field Characterisation of Strain Localisation Evolution in Sand under Triaxial Loading by In-situ X-ray Microtomography and 3D-volumetric Digital Image Correlation

Deformation in geomaterials (soils, rocks, concrete, etc.) is often localised, e.g., in the form of shear bands or fractures. In experimental analysis of the mechanical behaviour of such materials standard laboratory methods are insufficient as the majori
