Paper online (Int J Solids and Structures) on rough sphere contacts
Wei, D., Zhai, C., Hanaor, D., Gan, Y. (2020) Contact behaviour of simulated rough spheres generated with spherical harmonic. International Journal of Solids and Structures, in press. [DOI] Abstract: Normal contact behaviour between non-adhesive fractal rough particles is studied using a finite element method (FEM). A series of spherical grain surfaces with distinguished roughness features are…

Paper accepted (Eng Fracture Mech) on non-spherical particle breakage
Wei, D., Zhao, B., Dias-da-Costa, D., Gan, Y. (2019) An FDEM study of particle breakage under rotational point loading. Engineering Fracture Mechanics. In press. [DOI] Abstract: The most commonly adopted method to test the strength of single sand particles is based on platen experiments. This setup tends to align the loading direction towards the particle minimum…
