Presentation / Conference Contribution
Xie, Y. H., Yang, Z. X., & Barreto, D. (2016, August). The Influence of Particles’ Aspect Ratio on the Shear Behaviour of Granular Materials. Presented at 7th International Conference on Discrete Element Methods, Dalian, China

The mechanical response of granular material depends both on the material properties (e.g. stiffness, anisotropy, permeability, etc.) and particle geometry (shape, roughness, etc.). This paper presents a study of the effect of particle shape (i.e. as... Read More about The Influence of Particles’ Aspect Ratio on the Shear Behaviour of Granular Materials.

Shear wave dispersion in mechanically self-similar gel networks (1998)
Journal Article
Williams, P. R., & Williams, R. L. (1998). Shear wave dispersion in mechanically self-similar gel networks. Journal of Physics D: Applied Physics, 31(9), 1083

A study of viscoelastic shear wave dispersion in a simulated gelation process involving mechanically self-similar nodal networks is reported. The network formed at the gel point (the infinite network cluster, or `critical gel') shares a common struct... Read More about Shear wave dispersion in mechanically self-similar gel networks.

A modified form of the Gross-Marvin ladder model is used to simulate gelation processes in which α, the viscoelastic stress relaxation exponent in the Gel Equation, can be varied in the range O

Effect of Vortices on Liquid Outflow from Vessels (1995)
Journal Article
Harvey, R., & Kubie, J. (1995). Effect of Vortices on Liquid Outflow from Vessels. Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 209(5), 363-370. https://doi.org/10.1243/pime_proc_1995_209_164_02

This paper considers the effect of vortices on liquid outflow from open vessels. One of the simplest possible arrangements is investigated: an axisymmetric vertical cylindrical vessel with an outlet in its base. A simple spiral vortex is either intro...
