Model Fitting for Determining the Parameter of the Pore Size Distribution (2023)
Presentation / Conference Contribution
Imre, E., Mwinken, D. K., & Barreto, D. (2023, November). Model Fitting for Determining the Parameter of the Pore Size Distribution. Presented at 9th International Scientific Conference on Advances in Mechanical Engineering (ISCAME 2023), Debrecen, Hungar

The computation of the SWCC requires prior estimation of the pore-size distribution (POSD) which is computed from the PSD. The process described in detail by [1-3]. It needs a value of a which is a model parameter related to particle shape and orient... Read More about Model Fitting for Determining the Parameter of the Pore Size Distribution.

Particle size distribution induced fabric effects on the onset and post liquefaction behaviours of soils (2023)
Presentation / Conference Contribution
Leak, J., & Barreto, D. (in press). Particle size distribution induced fabric effects on the onset and post liquefaction behaviours of soils. In Proceedings of the XVIII ECSMGE 2024

Liquefaction in soils is a detrimental phenomenon. Microscale behaviours and their influence on the macroscale response during and after the onset of liquefaction are not well understood. In particular, how contact behaviours effect macroscale proper... Read More about Particle size distribution induced fabric effects on the onset and post liquefaction behaviours of soils.

The use of grading entropy in assessing granular soil hydraulic conductivity (2023)
Presentation / Conference Contribution
Feng, S., Vardanega, P., Ibraim, E., Barreto, D., & Imre, E. (2023). The use of grading entropy in assessing granular soil hydraulic conductivity. In A. Zhussupbekov, A. Sarsembayeva, & V. N. Kaliakin (Eds.), Smart Geotechnics for Smart Societies: Proceed

Hydraulic conductivity is an important geotechnical engineering property as it is linked to the performance of many geo-structures. This study used a recently compiled granular soil database (CG/KSAT/7/1278) to evaluate the best fit probability densi...
