Summary, in English

Shear banding in sand is an emergent fine-scale mechanism whose characteristic length scale is only a few particles. X-ray scanning a sand specimen under loading allows the analysis of the kinematics of individual grains and grain contacts during deformation. This paper summarises results from one such test performed on Hostun sand, and discusses some key issues that must be addressed in order to obtain accurate and physically meaningful results.
