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...

Grading curves and internal stability (2019)
Presentation / Conference Contribution
Imre, E., Barreto, D., Talata, I., Baille, W., Rahemi, N., Goudarzy, M., Lőrincz, J., & Singh, V. (2019, August). Grading curves and internal stability. Presented at MAFIOK 2019 - Matematikát, Fizikát És Informatikát Oktatók, Dunaújváros, Hungary

The measured grading curve is an empirical distribution function, a step function. This is considered here as a discrete distribution with fixed statistical cells. In the grading entropy theory it is characterized by the... Read More about Grading curves and internal stability.

Preliminary study on the relationship between dry density of sands and the grading entropy parameters (2019)
Presentation / Conference Contribution
Imre, E., Lorincz, J., Trang, P., Csonka, I., Kaczvinszki-Szabó, V., Telekes, G., Goudarzy, M., Rahemi, N., Baille, W., Schanz, T., Barreto, D., Fityus, S., & Singh, V. (2019, September). Preliminary study on the relationship between dry density of sands and the grading entropy parameters. Presented at The XVII European Conference on Soil Mechanics and Geotechnical Engineering, Reykjavik, Iceland

Some earlier data were analysed, searching the relation between the minimum dry density emax and the two grading entropy parameters (mean log diameter and fraction number characteristic). The data were split into two components. The first... Read More about Preliminary study on the relationship between dry density of sands and the grading entropy parameters.

Reanalysis of some in situ compaction test results (2019)
Presentation / Conference Contribution

A note on seismic induced liquefaction (2019)
Presentation / Conference Contribution
Imre, E., Lőrincz, J., Trang, P., Barreto, D., Goudarzy, M., Rahemi, N., Baille, W., Schanz, T., & Singh, V. (2019, September). A note on seismic induced liquefaction. Presented at The XVII European Conference on Soil Mechanics and Geotechnical Engineering, Reykjavik, Iceland

Any particle size distribution can be characterized by two parameter pairs (derived from the statistical entropy formula of discrete distributions) more effectively than simple diameter values (i.e., d50). The first entropy parameter is a conti... Read More about A note on seismic induced liquefaction.

Use of Compaction Grouting as Ground Improvement Technique in Compressible Solid Waste Landfill (2019)
Presentation / Conference Contribution
Tsitsas, G., Dimitriadi, V., Barreto, D., & Ciortan, R. (2019, September). Use of Compaction Grouting as Ground Improvement Technique in Compressible Solid Waste Landfill. Presented at The XVII European Conference on Soil Mechanics and Geotechnical Engineering, Reykjavik, Iceland

Ground improvement methods are increasingly being used as means
to control settlements and improve the shear strength of foundation soils. The compaction grouting (CG) method is a ground improvement method that is used as means... Read More about Use of Compaction Grouting as Ground Improvement Technique in Compressible Solid Waste Landfill.

X-ray tomography of sand-rubber mixtures (2019)
Presentation / Conference Contribution
Fonseca, J., Riaz, A., & Barreto, D. (2019). X-ray tomography of sand-rubber mixtures. In International Conference on Tomography of Materials and Structures Australia

The behavior of sand-rubber mixtures is controlled by the mechanisms taking place at the grain scale. Here, we use a mixture of shredded tire and a silica sand with similar grain sizes to investigate granular behavior under one-dimensional compressio...

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

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.
