WebApr 10, 2024 · Shear tests were carried out on three sands of different grain sizes interfacing with geogrids of five different aperture sizes and three different aperture shapes. Through these tests, interface shear response with a wide range of aperture ratio and different shapes of geogrids is understood. WebThe purpose of the direct shear test of soil is to obtain its ultimate shear resistance, its angle of internal friction, its cohesion, and its shear …
