... reinforcement were evaluated regarding the particle shape parameters of granular materials. Geosynthetics Geotextile Particle shape effect Direct shear test Interface friction Overall regularity Two shapes of sand soil were utilised, namely spherical and crushed sand, to investigate...

... Interface friction Membrane effect Arching theory In the current investigation, soil arching is a term used to describe a range of phenomena in which stresses within the soil between piles are redistributed as the soil tries to establish equilibrium by transferring loads into stiffer elements...

...Y.P. Vaid; N. Rinne The influence of soil particle shape, confining pressure and the amount of relative displacement on the value of the interface friction angle are studied in the laboratory using a ring shear apparatus. Two quartz sands, one angular and the other rounded, with two geomembranes...
