... investigation of the effects of particle morphology on sand interface friction angle using a Bromhead ring shear device. We tested three sands –fine silica sand, Hokksund sand, and Ottawa sand—against a smooth steel interface, medium rough sandpaper, and rough sandpaper under normal stresses ranging from 10–50...

... properties relevant to pipeline-seabed friction on sandy seabeds. The paper is underpinned by a new database that demonstrates the driving parameters that influence interface friction in granular materials. By accurately quantifying shear resistance along the pipe-soil interface under low normal stresses...
