TL;DR: In this article, a pair of 8 mm spherical grains of calcite, linked by a Portland cement, are analyzed experimentally at a local scale (cement-grain interface) during mechanical testing.

TL;DR: In this article, an etude experimentale de caracterisation du comportement mecanique a l'echelle locale du beton sain et degrade par lixiviation is presented.

TL;DR: In this article, the authors identify the spatial distribution of material properties and local stress fields using an inverse identification method based on the constitutive equation gap (CEG), which is based both on minimization of a cost function equal to the sum of the potential and complementary energies, and on the deviation between the measured and computed strain fields.

TL;DR: The methode d'Eigenerosion developpee par Pandolfi et Ortiz as mentioned in this paper combines l'approche variationnelle de Francfort et Marigo and a methode de type ((killing element)) for permettre une simulation rapide et efficace de la fissuration des materiaux homogenes.

TL;DR: In this paper, an iterative procedure is used to identify the local stress fields and the material properties distributions using full-field measurement techniques, and then the method was applied on noisy measured displacement fields to assess its robustness.
