Discrete element methods are important tools for investigating the mechanics of granular materials. In two dimensions, the reliability of these numerical approaches is increasingly being challenged, because they cannot take into account all the factors involved in the behavior of a granular medium. With new concepts, such as high performance parallel computing and 3D visualization, it is now possible to conduct numerical simulations of granular materials made up of several thousands of particles, and also to follow the evolution of the various parameters involved in the behavior of a granular medium. Experimental tests have been carried out to validate the results obtained by using a virtual laboratory. This paper presents the earlier results obtained in our 3D Virtual Laboratory on the response of specimens of glass beads of uniform size during shear tests. Good agreement was achieved between the virtual simulations and the experimental tests. This work highlights the possibility of using a new 3D virtual laboratory for dynamic simulation. This approach could be of significant value in improving the verification, validation, and communication of the simulation results of discrete element methods, which can in turn make the simulations more credible and thus useful in decision making.
