SHEAR PHENOMENA IN NATURAL GRANULAR MATERIALS.

Abstract

An experimental and theoretical study of the shear behavior of noncohesive macroparticle systems. It deals particularly with the effect of shape and, to a certain extent, mineral composition of the particles on the parameters of the macromeritic shear equation. Of the different available methods for expressing particle shapes those were found most practical that are based on the maximum and minimum densities obtained with simple standardized packing methods. The minimum densities thus obtained corresponded closely with the critical void ratios derived from shear tests. The problem of the previously reported negative values for minimum void ratios, computed from experimental data with the macromeritic shear equation, was solved, and the theoretical validity of this practically proven equation was demonstrated.
