On the Deformation of Granular Material

Abstract

SynopsisIn granular material, the deformation of a body is much more complicated than that in continuous media it inevitably acompanies the propagating process of compression.After the propagation process is 'finished,-the distribution,of .void in the ,body is nearly uniform and is considered to attain to a certain favourable state , so that in :this stage of deformation microscopical study of deformation can be performed.The hydrostatistical compression of the material was studied from this point of view and ana pproximate relationship between the compression and the pressure in case of confined compression of sand was obtained by applying the result of the study in the previous paper to the problem. This relationship is that already given by authors.
