A Grading Entropy Review of PSD-Based Frost Susceptibility Criteria (2024)
Conference Proceeding
Leak, J., Barreto, D., Wright, C., Bernal Sanchez, J., & Imre, E. (2024). A Grading Entropy Review of PSD-Based Frost Susceptibility Criteria. In T. M. Evans, N. Stark, & S. Chang (Eds.), Geo-Congress 2024: Soil Improvement, Sustainability, Geoenvironmental, and Cold Regions Engineering (714-724). https://doi.org/10.1061/9780784485330.072

Particle size distribution (PSD) is recognised among geotechnical engineers as an informative soil descriptor, and often used to predict geomechanical behaviours. However, the effectiveness of PSD to characterise frost action is debatable. Existing c... Read More about A Grading Entropy Review of PSD-Based Frost Susceptibility Criteria.

Exploring the Use of Rock Flour for Sustainable Peat Stabilisation (2024)
Conference Proceeding
Bernal-Sanchez, J., Coll, J., Leak, J., & Barreto, D. (2024). Exploring the Use of Rock Flour for Sustainable Peat Stabilisation. In Geo-Congress 2024: Soil Improvement, Sustainability, Geoenvironmental, and Cold Regions Engineering (450-460). https://doi.org/10.1061/9780784485330.046

This paper aims to investigate the mechanical behaviour of peat stabilised with glacial rock flour for foundation construction. Peat, a natural organic soil, presents challenges for construction due to its high compressibility and low bearing capacit...

Using grain size distribution to estimate permeability (2023)
Conference Proceeding
Imre, E., Bálint, Á., Houng, D. T. Q., López, L. L., Répássy, L., Mwinken, D. K., …Feng, S. (in press). Using grain size distribution to estimate permeability. In Proceedings of the XVIII ECSMGE 2024

This study examines the saturated water permeability using samples of loose and dense 2-fraction coarse sand mixtures. Besides the non-normalised entropy variables some additional parameters like density, diameter descriptors are used to characterize...

Particle size distribution induced fabric effects on the onset and post liquefaction behaviours of soils (2023)
Conference Proceeding
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.

A DEM study on the effect of inherent variability of assemblies of spherical particles (2023)
Conference Proceeding
Leak, J., & Barreto, D. (2023). A DEM study on the effect of inherent variability of assemblies of spherical particles. In Proceedings 10th NUMGE 2023: 10th European Conference on Numerical Methods in Geotechnical Engineering. https://doi.org/10.53243/NUMGE2023-388

This study presents DEM simulations of assemblies of spheres using periodic boundaries to assess the effect of inherent sample variability. DEM specimens with different particle size distributions (PSDs) were randomly generated, and then isotropicall...

Revisiting Hardin’s parameters for the quantification of particle breakage – A statistical entropy approach (2021)
Conference Proceeding
Leak, J., Barreto, D., Dimitriadi, V., & Imre, E. (2021). Revisiting Hardin’s parameters for the quantification of particle breakage – A statistical entropy approach. In Powders & Grains 2021 – 9th International Conference on Micromechanics on Granular Media. https://doi.org/10.1051/epjconf/202124907001

It is well recognised that particle breakage in granular materials is affected by stress level, stress path, initial density, and particle size distribution (PSD), amongst others. Furthermore, it has been shown that breakage has a significant influen... Read More about Revisiting Hardin’s parameters for the quantification of particle breakage – A statistical entropy approach.

Grading entropy coordinates and criteria for evaluation of liquefaction potential (2019)
Conference Proceeding
Barreto Gonzalez, D., Leak, J., Dimitriadi, V., McDougall, J., Imre, E., & Lőrincz, J. (2019). Grading entropy coordinates and criteria for evaluation of liquefaction potential. In Earthquake Geotechnical Engineering for Protection and Development of Environment and Constructions (1346-1353). https://doi.org/10.1201/9780429031274

Several methods are commonly used for the evaluation of liquefaction potential in soils. These include criteria based on SPT and CPT tests, shear wave velocity measurements and gradation limits, amongst others. This study applies the concept of gradi...
