2014 Des mesures de module d'Young par la méthode de flexion trois points pour des aérogels de silice sont présentées. Le comportement élastique est étudié en fonction de la densité apparente des matériaux. L'analyse de ces résultats expérimentaux est effectuée en utilisant l'analogie avec un système de percolation. Abstract. 2014 Measurements of the Young modulus of silica aerogels are performed using the three points flexural technique. The elastic behaviour is studied as a function of the apparent density of the materials. The analysis of the experimental results is made in terms of a percolating system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
