Abstract Based on the discrete element method and hydrostatics theory, an improved Archimedes principle is proposed to
study the rules pertaining to resistance changes during the penetration process of an intruder into the particulate
materials. The results illustrate the fact that the lateral contribution to the resistance is very small, while the
tangential force of the lateral resistance originates from friction effects. Conversely, the resistance of particulate
materials on the intruder mainly occurs at the bottom part of the intruding object. Correspondingly, the factors that
determine the resistance of the bottom part of the intruding object… More >
