The aim of the paper is to present a study of strain localization in Fontainebleau sandstone. To detect strain inhomogeneity, comparisons between measurements of strain and displacement at multiple locations have been done. A "rst series of tests have been performed on cylindrical samples. However, the results obtained show that the procedure followed is not systematically e$cient. Thus, it was decided to use prismatic samples. In order to control the initiation of strain localization and follow the shear banding up to the macroscopic failure, a last series of tests were performed on prismatic specimens containing a small hole. The shear band characteristics (onset, orientation, width) are given for all these tests on prismatic specimens. Their variation with con"ning pressure is emphasized. Finally, some details on the deformation mechanisms inside the bands are provided by means of visual observations.

Inhomogeneous flow in metallic glasses is studied in this paper within the context of continuum mechanics, Motivated by similar work for elastic-plastic solids, the possibility of strain localization into a shear band is investigated for a metallic glass which is modelled as a nonlinear viscoelastic
