Abstract

In order to examine the deformation mode and the stress state according to the specimen shape in the direct shear test (DST), a series of the three-dimensional DEM (distinct element method) simulations of the DST for sandy soils were carried out with the circular and the rectangular specimens. From the obtained results, the deformation mode of the rectangular specimen was under the plane strain condition, while the deformation mode of the circular specimen could not be explained as a plane strain condition. In addition, the principal stress states around the potential shear plane were analyzed and discussed by means of the analysis of the soil particle level.
