Journal Article
Leak, J., Dimitriadi, V., Barreto, D., Bernal-Sanchez, J., & Imre, E. (2025). Establishing a Relationship between Particle size distribution & Thaw weakening Susceptibility in Soils. Cold Regions Science and Technology, 231, Article 104423. https://doi.org/10.1016/j.coldregions.2025.104423

Susceptibility to frost action in soils is an important consideration in cold and seasonably cold regions. Whilst the particle size distribution (PSD) is commonly used to measure susceptibility to frost action, this method is typically seen as unreli...

Quantifying Particle Breakage and Its Evolution Using Breakage Indices and Grading Entropy Coordinates (2022)
Journal Article
Leak, J., Barreto, D., Dimitriadi, V., & Imre, E. (2022). Quantifying Particle Breakage and Its Evolution Using Breakage Indices and Grading Entropy Coordinates. Geotechnics, 2(4), 1109-1126. https://doi.org/10.3390/geotechnics2040052

Particle breakage in soils is a well-recognised behaviour. Conventional methods for quantifying the breakage process rely on calculating the area between the particle size distribution (PSD) curves produced before and after crushing. A key aspect of...

Revisiting Hardin’s parameters for the quantification of particle breakage – A statistical entropy approach (2021)
Presentation / Conference Contribution
Leak, J., Barreto, D., Dimitriadi, V., & Imre, E. (2021, July). Revisiting Hardin’s parameters for the quantification of particle breakage – A statistical entropy approach. Presented at Powders & Grains 2021 – 9th International Conference on Micromechanics on Granular Media, Buenos Aires (Virtual), Argentina

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.
