Abstract:A large amount of research has been done on conforming surfaces in rock joints as well as on the contact between individual grains, however, not much exist in nonconforming contact surfaces subjected to friction, such as flat contacts between ballast particles, stone columns or riprap; applications that involve the use of coarse gravel subjected to low vertical stresses. Therefore, this article aims to study changes in contact properties between non-conforming flat contacts between large geomaterial particles … Show more
