Opis:: The aim of this article is to compare experimentally determined strains of sand with theoretical calculations made on the base of the theory of hypoplasticity. During the study `Skarpa' sand was examined in the triaxial apparatus with local measurement of vertical and lateral strains. Results obtained were used to calibrate 8-parameter von Wolffersdorff model. Subsequently, the behaviour of loose and dense sandy samples subjected to different stress paths was predicted.

Opis:: 3D formulation of incremental relations, describing pre-failure deformations of granular soils, is presented. The starting point are respective equations formulated previously for the axi-symmetrical configuration, as that in the tri-axial apparatus. These relations, proposed for particular configuration, are generalized in the form of tensor equations for the strain increments. Similarly, the loading/unloading criterion and the instability line have been generalized for 3D conditions. A kind of cross-isotropy of granular soil is taken into account. Then, the incremental stress-strain relations for the plane strain state are re-derived from general equations, as such conditions are most often used for simulations of practically important problems. The procedure proposed in this paper is practically oriented, as the soil parameters can be determined just from the tri-axial tests.
