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.

Presentation / Conference Contribution
Barreto Gonzalez, D., Leak, J., Dimitriadi, V., McDougall, J., Imre, E., & Lőrincz, J. (2019, June). Grading entropy coordinates and criteria for evaluation of liquefaction potential. Presented at 7th International Conference on Earthquake Geotechnical Engineering, Rome, Italy

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...

Experimental assessment of stiffness and damping in rubber-sand mixtures at various strain levels (2019)
Presentation / Conference Contribution
Bernal-Sanchez, J., McDougall, J., Barreto, D., Marinelli, A., Dimitriadi, V., Anbazhagan, P., & Miranda, M. (2019, June). Experimental assessment of stiffness and damping in rubber-sand mixtures at various strain levels. Presented at 7th International Conference on Geotechnical Earthquake Engineering, Rome

The dynamic properties of shredded rubber-soil mixtures (ShRm), comprising a sub-rounded quartz sand combined with small rubber shreds at 0, 10, 20, 30% by mass, were investigated. Testing ranged from small strain, in resonant column apparatus, to la... Read More about Experimental assessment of stiffness and damping in rubber-sand mixtures at various strain levels.

Particle-scale interaction in sand-rubber mixtures and their influence on energy dissipation mechanisms (2019)
Journal Article
Fonseca, J., Riaz, A., Bernal-Sanchez, J., Barreto Gonzalez, D., McDougall, J., Miranda Manzanares, M., Marinelli, A., & Dimitriadi, V. (2019). Particle-scale interaction in sand-rubber mixtures and their influence on energy dissipation mechanisms. Géotechnique Letters, 9(4), 1-6. https://doi.org/10.1680/jgele.18.00221

Sand-rubber mixture (SRm) behaviour is affected by rubber content (RC) whilst dissipation in sands is caused by inter-particle sliding. Dissipation in SRm is as, or more significant than in sands. However, the mechanisms of dissipation in SRm are not... Read More about Particle-scale interaction in sand-rubber mixtures and their influence on energy dissipation mechanisms.

Modern seismic codes dictate that the use of shallow foundations on liquefiable soils may be considered only after appropriate ground improvement. No further instructions are given regarding the improvement depth, or what changes if the surface layer...
