Abstract
This paper shows the comparison of two anisotropic models: an advanced rotational hardening model that accounts for both inherent and plastic strain induced anisotropy (S-CLAY1) and the Sekiguchi-Ohta model which accounts for inherent anisotropy only. In the paper, two-dimensional behaviour of a benchmark embankment on soft soils is modelled with the PLAXIS fi nite element program using user-defi ned implementations of the S-CLAY1 and Sekiguchi-Ohta models. The same problem is then reanalysed by switching off the evolution in anisotropy in the S-CLAY1 model.
