Abstract

Cette étude propose une méthodologie expérimentale afin d’identifier les propriétés mécanique élastiques d’anneaux supraconducteurs. Des essais de traction diamétrale associés à une technique de mesure champs de déplacements ont été effectués sur des échantillons. Les champs de déformations ont ensuite été obtenus à partir des champs de déplacements par différentiation numérique. Enfin, les quatre modules élastiques orthotropes dans le plan des enroulements ont été identifiées à l’aide la méthode des champs virtuels.
 
This study deals with an experimental methodology developed in order to identify the elastic properties of superconducting ring-shaped windings. Mechanical tensile tests were conducted on specimens associated to a full-field displacement measurement technique. Strain fields were then obtained from the measured displacement fields by numerical differentiation. Finally, the four in-plane orthotropic stiffnesses of the windings were determined using the Virtual Fields Method
