抄録: It is fairly important to estimate a feature of progressive failure and a dilatancy characteristics of granular material such as sand, and a development process of shear band has been recently noteworthy concerning with progressive failure in the micro-mechanics. This paper first describes the test results of direct shear test for grass beads which have equivalent diameters. The paper next deals with a numerical simulation for the above tests using by Distinct Element Method (hereafter refers to as DEM) developed by Cundall, P. A. (1971) at first as a computer model for simulating progressive large scale movement in blocky rock systems. It has been clarified that DEM modified by one of the authors can estimate sufficiently the feature of progressive failure and the dilatancy characteristics of granular material from the comparison with observed and calculated behavior of granular material under direct shear.
