de réaliser la simulation numérique de l'expérience à l'aide d'un code aux éléments finis afin d'évaluer les différents éléments du montage expérimental (explosifs,...), de comprendre le chargement mécanique réellement appliqué au matériau et enfin de développer la méthode d'interprétation des données expérimentales la plus adaptée. Abstract. The dynamic loading applied to a material during an expanding ring experiment associates the propagation of a shock wave with a dynamic uniaxial tension. It seems judicious to perform a numerical simulation of the test with a finite element code in order to evaluate the various elements of the experimental assembly (explosive,...), to understand the mechanical loading really ap...
