Effect of the Surface Roughness on the Shear Strength of Granular Materials in Ring Shear Tests [PDF]
Applied Sciences, 2019 Surface roughness plays an important role in estimating the shear strength of granular materials. A series of ring shear tests with different surface roughnesses (i.e., smooth and rough surfaces) were performed.
