Experimental Versus Finite Element Approach to Study Scale Dependent Features in Granular Materials’ Stress and Deformation Fields

This paper presents selected results of physical model tests on large granular assembly and finite element analysis of the same configuration. Standard Mohr-Coulomb model was employed as a soil model. The comparison between experimental strain fields and FEM simulations was performed. It was found that the general alignment of strain localization pattern (dilation bands) belongs to macro scale features rather and is dominated by a test boundary conditions and the separated compaction bands may result entirely from granular nature of the sample.
