Investigation of three-dimensional granular stresses in pyramidal container after filling

Abstract

The discrete element simulation was performed to evaluate granular stresses in pyramidal container after the filling. The 3D stress fields were obtained on the basis of a micromechanical approach by calculating inter-particle contact forces and their subsequent homogenization in the given volume of material. Stress distributions were con-firmed the continuum-based indications. According to the results obtained, the stress distribution factor was corrected relying on the influence of three-dimensionality in the frame of the differential slice approach.
