Descripción
The use of appropriate pressure cells together with a reliable system to mount them in the silo wall is important to facilitate the later interpretation of the results. Plate-type normal pressure cells without fluid behind have been used in an installation of three full-scale steel silos with different eccentric hoppers. Local imperfections introduced when normal pressure cells were mounted on the wall of these silos were found to be responsible of overpressures registered during the storage process. Wheat and maize were tested in these silos. A discrete element model has been developed in order to find out the effects that explain these overpressures. The development of a sheared zone responsible of dilatancy effects and the concentration of forces, as a result of trapped particles within the local imperfection zone, were observed during the sliding of the stored material along the silo wall. The particle size distribution was also found to be a significant factor affecting the registered pressure.
