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 additi...
Particle size distribution induced fabric effects on the onset and post liquefaction behaviours of soils
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...
Quantifying Particle Breakage and Its Evolution Using Breakage Indices and Grading Entropy Coordinates
Journal Article
