B-spline based boundary conditions in the material point method (2018)
Journal Article
Bing, Y., Cortis, M., Charlton, T., Coombs, W., & Augarde, C. (2019). B-spline based boundary conditions in the material point method. Computers and Structures, 212, 257-274. https://doi.org/10.1016/j.compstruc.2018.11.003

The material point method is an increasingly popular method for tackling solid mechanics problems involving large deformations. However, there are issues associated with applying boundary conditions in the method and, to date, no general approach for...

Centrifuge testing to verify scaling of offshore pipeline ploughs (2018)
Journal Article
Robinson, S., Brown, M., Matsui, H., Brennan, A., Augarde, C., Coombs, W., & Cortis, M. (2019). Centrifuge testing to verify scaling of offshore pipeline ploughs. International Journal of Physical Modelling in Geotechnics, 19(6), 305-317. https://doi.org/10.1680/jphmg.17.00075

Offshore pipeline ploughs have previously been modelled at 1g with small 1:50 scale models designed to derive the parameters required for prediction of ploughing in terms of tow force requirements and potential advance rates. This was scaled up to pr... Read More about Centrifuge testing to verify scaling of offshore pipeline ploughs.

The effect of ambient humidity on the stiffness and strength of a hyper-compacted silty clay for earth building (2018)
Presentation / Conference Contribution
Cuccurullo, A., Gallipoli, D., Bruno, A., La Borderie, C., Augarde, C., & Hughes, P. (2018, August). The effect of ambient humidity on the stiffness and strength of a hyper-compacted silty clay for earth building. Presented at 7th International Conference on Unsaturated Soils, Hong Kong, China

The effect of pore suction and water content on the engineering properties of partially saturated soils has been extensively studied by geotechnical researchers. It is well known that unsaturated soils become stiffer, stronger and less permeable as s...

Preliminary study on use of biopolymers in earthen construction (2018)
Presentation / Conference Contribution
Muguda, S., Booth, S., Hughes, P., Augarde, C., Perlot, C., Bruno, A., & Gallipoli, D. (2018, August). Preliminary study on use of biopolymers in earthen construction. Presented at 7th International Conference on Unsaturated Soils, Hong Kong, China

Biopolymers are known to achieve significant soil stabilisation when working with small quan-tities. There have been studies understanding their effects on permeability, strength, compressibility and dura-bility, however, there are few studies explor...
