Localisation has been modelled numerically in the plane strain elemental test using two different frictional constitutive models. It is demonstrated that for this simple problem the use of Mohr-Coulomb analysis is adequate to model the formation of shear planes in drained soils. However these results are not the same as those obtained using the Monot double-hardening model. When analysing an undrained soil only the double-hardening model was investigated. It is demonstrated that the dilatancy or contractancy of the soil model has a very strong influence on the resulting deformation pattern. In particular, it was found that localisation did not occur for the dilatant soil unless a cavitation limit was applied, even when a strain-softening dilatant soil model was implemented.(A)
