This paper deals with the application of an elasto-viscoplastic version of the NAHOS model built in the Department of Geotechnics, Silesian University of Technology. The model has been developed since 1997. It is able to realistically describe the material response to complex load paths. It can also describe non-linear characteristics within the small strain range and the effect of the rate on the process. The elastoplastic NAHOS model was presented in detail at the Polish-French colloquium in Wrocław, Poland, in 2003. The model is based on the results of cyclic triaxial tests, for the purposes of this article performed on kaolin samples without drainage, following back pressure saturation and then isotropic consolidation. The paper quotes these results and briefly presents model equations and the procedure of model's implementation for the title problem.
