The theory of continuous media is not sufficient to explain the behaviour of granular materials, so it is necessary to consider the discrete nature of such media. A method that answers such questions is the distinc element method. The numerical simulation of the behaviour of Schneebeli analogical material (2D) and of granular materials (3D) is done by the distinct element method and by using the trubal program in order to reproduce numerically, certain experimental tests of the characterization of granular materials. The biaxial compression test and the simple shear test are done with rolls of PVC and glass and the trixial test is simulated with glass balls. The experimental results validate the method used and enable us to obtain the chara...
