A model for the forecasting of the propagation the technological impacts

Abstract

The paper subject is the application of the elasto – viscoplastic version of the NAHOS model, which has been developed in Char of Geotechnics Silesian University of Technology since 1997. This model is able to realistically describe the material answer for complex load paths with particular consideration non-linear characteristics in small strain range and the influence of time for run of a process. The elasto – plastic NAHOS model was detailed presented in Polish – French colloquium in Wroclaw in 2003. In article there are showed the results of cyclic triaxial tests, which are premises of the described model. All triaxial tests were performed on kaolin samples without drainage, after watering, back pressure method and isotropic consolidation. A concise model equations and a procedure for implementation of this model to analysis the title problem si presented.
