Book Description

Geomechanics from Micro to Macro contains 268 papers presented at the International Symposium on Geomechanics from Micro and Macro (IS-Cambridge, UK, 1-3 September 2014). The symposium created a forum for the dissemination of new advances in the micro-macro relations of geomaterial behaviour and its modelling. The papers on experimental investigations show findings from micro-scale experiments, non-destructive imaging, element testing (coarse grained materials, fine grained materials and mixtures), physical model tests and field tests. The subjects of the investigations include particle effects (shape, size and grading), partial saturation, creep and aging, fluid-grain coupling, biological and chemical effects, and thermal effects. The papers on discrete based modelling examine pre- and post-failure behaviour, particle shapes and size effects, particle crushing, dynamic behaviour, bonding effects, fracturing and fragmentation, interface behaviour, and fluid-grain coupling. The contributions on continuum based modelling include stress-strain relationships, multi-scale modelling, multiphase modelling, fluid flow modelling, and numerical modelling based on continuum based models and particle based models.

Geomechanics from Micro to Macro will be of interest to academics and engineers involved in granular physics, soil mechanics, rock mechanics, geotechnical engineering and geological engineering.
