Effect of Cementation on the Shear Strength of Tehran Gravelly Sand Using Triaxial Tests

Three-Dimensional Discrete Element Simulations of Direct Shear Tests

Using discrete element methods, geotechnical engineers can create “virtual laboratories” to simulate conventional laboratory tests. In this study, three-dimensional DEM simulations of direct shear tests are coupled with equivalent physical tests on steel balls. The macro-scale response of simulations is compared with the physical test results to validate the discrete element model and to gain i...

Permeability and Direct Shear Tests Characteristics of Railway Subballast

Permeability, filtration and shearing strength were widely considered to be the key properties in evaluating the performance of railway subballast. An investigation on these key properties of railway subballast was presented in this paper. A constant head permeability test and a middle scale direct shear test of railway subballast were conducted in the research, aiming to investigate the subbal...

Numerical Studies of Shear Banding in Interface Shear Tests using a New Strain Calculation Method

Strain localization is closely associated with the stress-strain behavior of an interphase system subject to quasi-static direct interface shear, especially after peak state is reached. This behavior is important because it is closely related to deformations experienced by geotechnical composite structures. This paper presents a study using two dimensional DEM simulations on the strain localiza...
