The paper presents selected results from an experimental testing program recently performed at the ESRF, where high resolution, fast X-ray micro tomography was used to evaluate the onset and evolution of strain localization in Callovo-Oxfordian argillite under deviatoric loading. In situ micro tomography allowed detailed observations of strain localization at different load levels. X-ray CT was complimented with 3D digital image correlation to obtain a sequence of incremental 3D strain fields of a deforming specimen.
