Quantifying the Evolution of Soil Fabric Under Different Stress Paths (2009)
Presentation / Conference Contribution
Barreto, D., O’Sullivan, C., & Zdravkovic, L. (2009, July). Quantifying the Evolution of Soil Fabric Under Different Stress Paths. Presented at AIP Conference Proceedings

It is well recognized that the macro-scale response of soils is anisotropic in terms of strength, stiffness, permeability, etc. The source of this anisotropy is thought to be an anisotropy of the material itself. This anisotropy can be quantified usi... Read More about Quantifying the Evolution of Soil Fabric Under Different Stress Paths.

Specimen generation approaches for DEM simulations. (2008)
Presentation / Conference Contribution
O'Sullivan, C., Barreto, D., & Zdravkovic, L. (2008, September). Specimen generation approaches for DEM simulations

Discrete Element Method (DEM) simulations ofelement tests cam provide significant insight into the micro-mechanics of soil response. It is well established that soil behaviour is strongly dependant on the initial density. Generation of particulate as... Read More about Specimen generation approaches for DEM simulations..

Evolution of soil fabric and its interpretation using different methods. (2008)
Presentation / Conference Contribution
Barreto, D. (2008, June). Evolution of soil fabric and its interpretation using different methods. Paper presented at British Geotechnical Association (BGA) Young Geotechnical Engineers' Symposium

Different methods to study the evolution of fabric anisotropy are presented. DEM simulations on assemblies of spheres subjected to different stress paths using a three-dimensional periodic cell are used for the analysis of these methods. The links be...
