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.

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.
