Abstract: Abstract This report investigated the effects of irregular particles on macroscopic and microscopic behaviour under triaxial compression tests for a range of various roundnesses. A multi-sphere method was employed to model the three-dimensional irregular particles… read more here.

Abstract: Abstract The heavy haul coal line of the South African railway network is facing a problem where ballast particles are becoming rounded, negatively affecting performance and thus leading to shorter planned maintenance cycles. This has… read more here.
