Abstract: The dynamics of rigid bodies was studies by long time, because this phenomenon is important in the seismic security of some types of structures. However, there are few experimental studies. This job shows the experimental test carried out at the Laboratório Nacional de Engenharia Civil (LNEC) of Portugal. Four blue granites stones were tested, each one with different geometrical characteristics, under harmonic and random motions. A numerical simulation was carried out with the Discrete Element Method (DEM). This method has shown to be a good tool in the study of the dynamics of rigid bodies. It was proposed a new methodology to find the parameters of the DEM by using the parameters of classical theory.
