Journal ArticleDOI
Discrete and continuum analysis of localised deformation in sand using X-ray mu CT and volumetric digital image correlation
Stephen Hall,Michel Bornert,Jacques Desrues,Yannick Pannier,Nicolas Lenoir,Gioacchino Viggiani,Pierre Bésuelle +6 more
TL;DR: In this paper, the onset and evolution of localised deformation processes in sand with grain-scale resolution was observed and quantified by combining state-of-the-art X-ray micro tomography imaging with 3D volumetric digital image correlation techniques.
Journal ArticleDOI
Volumetric Digital Image Correlation Applied to X-ray Microtomography Images from Triaxial Compression Tests on Argillaceous Rock
Nicolas Lenoir,Nicolas Lenoir,Michel Bornert,Jacques Desrues,Pierre Bésuelle,Gioacchino Viggiani +5 more
TL;DR: In this article, a set of triaxial compression tests on specimens of argillaceous rock were performed under tomographic monitoring at the European Synchrotron Radiation Facility in Grenoble, France, using an original experimental set-up developed at Laboratoire 3S.
Journal ArticleDOI
Multiscale modeling and characterization of granular matter: From grain kinematics to continuum mechanics
TL;DR: Granular sands are characterized and modeled in this article by explicitly exploiting the discrete-continuum duality of granular matter, and the evolution of key properties directly from the grain-scale mechanics and injecting it into a continuum description.
Journal ArticleDOI
Evidence for Hydraulic Vulnerability Segmentation and Lack of Xylem Refilling under Tension.
Guillaume Charrier,José M. Torres-Ruiz,Eric Badel,Régis Burlett,Brendan Choat,Hervé Cochard,Chloé E. L. Delmas,Jean-Christophe Domec,Steven Jansen,Andrew King,Nicolas Lenoir,Nicolas Martin-StPaul,Gregory A. Gambetta,Sylvain Delzon +13 more
TL;DR: The findings provide evidence that grapevine is unable to repair embolized xylem vessels under negative pressure, but its hydraulic vulnerability segmentation provides significant protection of the perennial stem.
Journal ArticleDOI
X-ray microtomography for studying localized deformation in fine-grained geomaterials under triaxial compression
Gioacchino Viggiani,Nicolas Lenoir,Nicolas Lenoir,Pierre Bésuelle,Marco Di Michiel,Stefania Marello,Jacques Desrues,Mogens Kretzschmer +7 more
TL;DR: Viggiani et al. as discussed by the authors used X-ray microtomography (with a spatial resolution of 14 μm) to evaluate the onset and evolution of shear banding in a fine-grained stiff soil under deviatoric loading.
