Abstract

A hypoplastic law is used for the FE simulations of two model tests with sand. In both model tests localization is observed. It is shown that void ratio scattering at initial state of the numerical simulations is of primary importance in order to model localization. A simple exponential frequency distribution, which is dependent of the sand density yields realistic results.
