Abstract: Contact tests on machined and natural granite showed that extensive plastic deformation which extends to the core shape is happening before the cross-over from the behaviour of an elastic rough surface to the Hertzian behaviour… read more here.

Abstract: Abstract The strength and deformation behaviour of granular soil is strongly dependent on its stress state and loading history. Due to the change of soil state, the plastic flow direction and loading direction are usually… read more here.

DOI: 10.1016/j.ijsolstr.2020.05.004
Abstract: Abstract The fragments from crushed rock are initially very angular. The erosion process causes the fragment shape to evolve from angular to well rounded and affects the mechanical behaviour of granular materials. This report explores… read more here.
