On the interface friction in direct shear test
Computers and Geotechnics, 2005Abstract Distinct element simulations for the direct shear box tests on a dense and a loose 2D sample of a mixture of binary diameter cylinders were performed. Special attention is focused on the friction between the internal surface of the shear box and the sample.

Sand-Nonwoven geotextile interfaces shear strength by direct shear and simple shear tests
Geomechanics and Engineering, 2015Soil-reinforcement interaction mechanism is an important issue in the design of geosynthetic reinforced soil structures. This mechanism depends on the soil properties, reinforcement characteristics and interaction between these two elements (soil and reinforcement).

Shear behaviour of a cement grout tested in the direct shear test
Construction and Building Materials, 2018Abstract Portland cement grouts are widely used in the mining industry to bond cable bolts with the surrounding rockmass. Numerous laboratory and field tests showed that bond failure of the cable/grout interface is the dominant failure mode. Previous research has found that shear behaviour of the grout along a pre-defined plane plays a significant ...

This paper summarizes the appropriate equipment and test procedure for ballast shear strength testing using the direct shear method (ASTM D3080 and D5321) and presents some typical results. To accomplish this ballast testing, a full-scale direct shear box was developed that can accommodate an approximately 1 m (3 feet) wide and 0.6 m (2 feet) deep ...

Development of a New Direct Shear Testing Apparatus
Rock Mechanics and Rock Engineering, 2009Politecnico di Torino and G.D.S. Instruments Ltd, UK has developed an innovative servo controlled direct shear apparatus named High Pressure Back Pressure Shear Apparatus-HPBPSA. The apparatus allows direct shear tests to be performed under closely controlled conditions in terms of axial load and back pressure applied to the specimen.

Experimental data from unreinforced direct shear tests on sand are presented to show the influence of the boundary conditions on the test measurements. The data and the theoretical considerations of the loading in the test show that a symmetrical direct shear test arrangement is preferable.
