Investigating the micro mechanics of cemented sand using DEM (2014)
Journal Article
de Bono, J. P., McDowell, G. R., & Wanatowski, D. (2015). Investigating the micro mechanics of cemented sand using DEM. International Journal for Numerical and Analytical Methods in Geomechanics, 39(6), https://doi.org/10.1002/nag.2340

The discrete element method has been used to investigate the micro mechanics of cemented sand. High pressure drained triaxial tests are modelled in 3D using a flexible membrane which allows the correct deformation to develop. Simulations with up to...

An insight into the yielding and normal compression of sand with irregularly-shaped particles using DEM (2014)
Journal Article
de Bono, J. P., & McDowell, G. R. (2015). An insight into the yielding and normal compression of sand with irregularly-shaped particles using DEM. Powder Technology, 271, https://doi.org/10.1016/j.powtec.2014.11.013

The micro mechanics of one-dimensional and isotropic normal compression of granular soil have recently been revealed using the discrete element method. By modelling soil grains as spheres and implementing a new crushing model, the authors have previo...

Discrete element modelling of rock communition in a cone crusher using a bonded particle model (2014)
Journal Article
Li, H., McDowell, G. R., & Lowndes, I. (2014). Discrete element modelling of rock communition in a cone crusher using a bonded particle model. Géotechnique Letters, 4(2), https://doi.org/10.1680/geolett.14.00006

It is known that discrete element method modelling (DEM) of rock size reduction can be achieved by two approaches: the population balance model (PBM) and the bonded particle model (BPM). However, only PBM has been successfully used in DEM modelling c... Read More about Discrete element modelling of rock communition in a cone crusher using a bonded particle model.

Investigating geogrid-reinforced ballast: Experimental pull-out tests and discrete element modelling (2014)
Journal Article
Chen, C., McDowell, G., & Thom, N. (2014). Investigating geogrid-reinforced ballast: Experimental pull-out tests and discrete element modelling. Soils and Foundations, 54(1), 1-11. doi:10.1016/j.sandf.2013.12.001

This paper presents an evaluation of the interlocking behaviour of geogrid-reinforced railway ballast. Experimental large box pull-out tests were conducted to examine the interaction between ballast and a biaxial geogrid. The discrete element method...

Discrete element modelling of a rock cone crusher (2014)
Journal Article
Li, H., McDowell, G. R., & Lowndes, I. (2014). Discrete element modelling of a rock cone crusher. Powder Technology, 263, https://doi.org/10.1016/j.powtec.2014.05.004

The feasibility of the discrete element method to model the performance of a cone crusher comminution machine has been explored using the particle replacement method (PRM) to represent the size reduction of rocks experienced within a crusher chamber....

DEM of triaxial tests on crushable sand (2014)
Journal Article
de Bono, J. P., & McDowell, G. R. (2014). DEM of triaxial tests on crushable sand. Granular Matter, 16(4), https://doi.org/10.1007/s10035-014-0500-x

This paper presents simulations of high-pressure triaxial shear tests on a crushable sand. The discrete element method is used, featuring a large number of particles and avoiding the use of agglomerates. The triaxial model features a flexible membran...

DEM of triaxial tests on crushable cemented sand (2014)
Journal Article
de Bono, J. P., McDowell, G. R., & Wanatowski, D. (2014). DEM of triaxial tests on crushable cemented sand. Granular Matter, 16(4), https://doi.org/10.1007/s10035-014-0502-8

Using the discrete element method, triaxial simulations of cemented sand consisting of crushable particles are presented. The triaxial model used features a flexible membrane, allowing realistic deformation to occur, and cementation is modelled using... Read More about DEM of triaxial tests on crushable cemented sand.
