ABSTRACT
Localized shear zones occur during shear deformation at contact of soils with construction materials (concrete, steel), and a proper modelling of foundation structures should consider the behaviour of these interfaces. A 1-D stress-strain relation for localized behaviour is proposed. It is based on the theory of hypoplasticity and it can take into account the influence of pressure and density on the mechanical response of granular materials. Nevertheless, no characteristic material length is included, thus the shear band width cannot be predicted. An application of the proposed contact relation in a FE calculation of a pull-out experiment is also shown.
