Dilatant Properties of Random Sphere Packing
The authors describe the dilatancy testing of granular media composed on similar spherical particles—glass balls, millet grains and peas. The testing included simple shearing and complex loading with continuous rotation of the strain tensor axes. The cyclic deformation enables partial elimination of...

Zusammenfassung: | The authors describe the dilatancy testing of granular media composed on similar spherical particles—glass balls, millet grains and peas. The testing included simple shearing and complex loading with continuous rotation of the strain tensor axes. The cyclic deformation enables partial elimination of defects of the initial stochastic packing and promotes its transition to a reversible state. The optimal relative density of a packing is presented for the discrete element analyses. |
