Abstract
The paper presents a number of numerical simulations of triaxial shear tests. The simulations have been made with the Generalised Interpolation Material Point method (GIMP, Bardenhagen & Kober 2004), which allows for modelling of large displacements, such as those occurring in shear bands. The simulations are assessed qualitatively and compared with available numerical results. Unconstrained compression tests on unsaturated soil specimens are also simulated. In all the analyses, the Mohr-Coulomb model, extended into the unsaturated regime, was used. The paper is part of a joint research program in the Centre for Geotechnical Science and Engineering which aims to assess and to validate the material point method for engineering purposes. © 2015 Taylor & Francis Group, London.
