[en] Strain localisation in soils and rocks has been studied extensively for the last 20 years. A part of
these studies have been devoted to the response of specimens submitted to tests in undrained situation. It was shown that shear banding can take place in both contractive and dilative specimens, with some special features due to the coupling between the granular skeleton and the pore fluid. In the paper, the relevance of the bifurcation criterion in shear band mode in the case of hydromechanical coupling is assessed by numerical study of the response of the constitutive model CLoE –the Hypoplastic model developed in L3S-Grenoble– in two kinds of numerical integration: local, i.e. at the material point level and global, i.e. in boundary value problems analyzed by finite elements.
