Abstract: In this talk we'll go from regular mechanical tests on dense sand samples, put them in an x-ray machine to reveal beautiful and complex shear band patterns, shrink the experiment so that we can simplify the mechanics and study sear banding at the grain scale. The information gathered at this scale is used to make a realistic numerical model of the studied sand allowing us to loop back to the main objective of the experiments -- to learn something about stress-strain behaviour at the continuum scale. A short introduction to x-ray tomography and digital image correlation will be given.
Short bio: Edward Andò is CNRS Research Engineer working in experimental mechanics and more precisely full field measurement techniques. He is passionate about measurement science in general and has been working among other things on the mechanics of granular media, developing techniques to reveal grain-scale quantities (but also studies rocks, clay...). He is a user and developer of x-ray and neutron tomography. Edward is a firm believer in open science -- since we're getting much more information about many fewer samples it's important to share tools and avoid black boxes to avoid a reproducibility crisis -- to this end he is a core developer of the free software "spam" Software for Practical Analysis of Materials. Edward is a co-founder and editor of the young journal Open Geomechanics.
