The discrete element method has been used to investigate the micro mechanics of shearing to a critical state on the loose and dense sides of critical. Isotropic compression has previously been modelled in 3D using a large number of particles and with... Read More about Micro mechanics of critical states for isotropically overconsolidated sand.

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. https://doi.org/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...

This paper presents an evaluation of the behaviour of geogrid-reinforced railway ballast. Experimental large box pull-out tests were conducted to examine the key parameters influencing the interaction between ballast and the geogrid. The experimental...

Discrete element modelling of uniaxial constant strain rate tests on asphalt mixtures (2013)
Journal Article
Cai, W., McDowell, G. R., & Airey, G. (2013). Discrete element modelling of uniaxial constant strain rate tests on asphalt mixtures. Granular Matter, 15(2), https://doi.org/10.1007/s10035-013-0396-x

Constant strain rate tests for a graded asphalt mixture under three constant strain rates have been undertaken in the laboratory. The Discrete Element Model has been used to simulate the laboratory tests with a numerical sample preparation procedure...
