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...
