(2010): Boundary effects on behaviour of granular material during plane strain compression
EUR J MECH A-SOLID. 2010; 29(1): 18-27. FullText FullText_BOKU

The paper investigates the boundary effect on the behaviour of granular materials during plane strain compression using finite element method. A micro-polar hypoplastic constitutive model was used. The numerical calculations were carried out with different initial densities and boundary conditions. The behaviour of initially dense, medium dense and loose sand specimen with very smooth or very rough horizontal boundary was investigated. The formation of shear zones gave rise to different global and local stress and strain. Comparisons of the mobilized internal friction, dilatancy and non-coaxiality between global and local quantities were made. (C) 2009 Elsevier Masson SAS. All rights reserved.
