Abstract

This paper describes how we tried to compute the most possible accurate stress and strain values, during a nominal working, in every desired point of a superconductive current limiter coiling's intricate structure. Because physical and geometrical specifications were rapidly varying ones with respect to loading forces' variation scale, it was not conceivable to mesh straight the device. The very different scales lead us to choose a finite element homogenization method for discretization of the problem. We used a so called averaging method which consists in splitting the "local" and "overall" field dependencies, so defining a "representative elementary volume". After description of the superconductive current limiter coiling, a brief description of the homogenization method implemented in EDF mechanics Code Aster©, we present results.
