Abstract

When studying the discreteness of granular materials, the size of the angle of repose can be used as an important parameter to study the stability of granular materials. In recent years, many scholars have studied the morphology of particles, but they are basically based on the regular shape of spheres and ellipsoids, which are very different from the actual particle shape, which leads to the measurement results not consistent with the actual results. Therefore, based on the above reasons, this paper mainly studied the influence of geometric shape for the Reposed Angle, the simulation experiment is carried for the Reposed Angle using the discrete element software EDEM, the Reposed Angle is measured for five different shape using slice cutting analysis method, and the experimental measurement has carried on for the Reposed Angle for each shape, SPC method is used to determine the reliability of the data. The results show that the size of the Reposed Angle increases gradually in the order of sheet, intermediate, horn, strip and equal square among the five studied shape, the mechanism is that the greater the number of internal contact is, can truly reflect the interaction and occlusal relationship, the more easily locked the particles are in the force chain, the more difficult to separate the particles are, the more stable the accumulation characteristics are.
