Many studies on strain localization of geomaterials have been carried out over the past few decades. Theoretical analysis and numerical models show that the dilatancy property strongly affects the onset of the deformation localization bands. The evolution of deformation bands, however, remains poorly known. In this work, we analyzed the...

We investigate the deformation localization at brittle-ductile transition in axisymmetric compression tests of rock analogue material GRAM1 made of bonded rigid particles. This transition in rocks (as well as in GRAM1) is recognized by the formation of a network of conjugate deformation localization bands in the postmortem rock samples and by a...
