Use of DEM and elastic stability analysis to explain the influence of the intermediate principal stress on shear strength (2013)
Journal Article
O'Sullivan, C., Wadee, M., Hanley, K., & Barreto, D. (2013). Use of DEM and elastic stability analysis to explain the influence of the intermediate principal stress on shear strength. Géotechnique, 63(15), 1298-1309. https://doi.org/10.1680/geot.12.p.153

One interesting aspect of soil response is the sensitivity of the mechanical behaviour to the intermediate principal stress. In this study, a fundamental mechanism that explains the influence of the intermediate stress ratio (b) on soil shear strengt...

Volumetric consequences of particle loss by grading entropy (2013)
Journal Article
McDougall, J., Imre, E., Barreto, D., & Kelly, D. (2013). Volumetric consequences of particle loss by grading entropy. Géotechnique, 63(3), 262-266. https://doi.org/10.1680/geot.sip13.t.002

Chemical and biological processes, such as dissolution in gypsiferous sands and biodegradation in waste refuse, result in mass or particle loss, which in turn lead to changes in solid and void phase volumes and grading. Data on phase volume and gradi... Read More about Volumetric consequences of particle loss by grading entropy.

Particle loss and volume change on dissolution: experimental results and analysis of particle size and amount effects (2013)
Journal Article
McDougall, J., Kelly, D., & Barreto, D. (2013). Particle loss and volume change on dissolution: experimental results and analysis of particle size and amount effects. Acta geotechnica, 8(6), 619-627. https://doi.org/10.1007/s11440-013-0212-0

Soil particles may be lost through dissolution, degradation or erosion. Regardless of the process of loss, there follows a change in soil structure both in terms of phase composition and grading. In this paper, the influence of size and amount of par... Read More about Particle loss and volume change on dissolution: experimental results and analysis of particle size and amount effects.

Quantifying stress-induced anisotropy using inter-void constrictions (2013)
Journal Article
Shire, T., O'Sullivan, C., Barreto, D., & Gaudray, G. (2013). Quantifying stress-induced anisotropy using inter-void constrictions. Géotechnique, 63(1), 85-91. https://doi.org/10.1680/geot.11.t.020

In particulate geomechanics it is common to quantify fabric anisotropy using contact and particle orientations. Measurement of void anisotropy is less common, most likely owing to the difficulties associated with defining individual voids. Here a Del...
