    Abstract

    Silver/BSCCO composite superconducting tapes are produced using BSCCO-2212 ceramic powder. The manufacturing process implies a large number of forming operations including drawing and rolling. The numerical simulation of the flat rolling process is of a great interest to anticipate the shape of the silver/composite tape. In order to achieve these goals, the plastic properties of superconducting BSCCO-2212 ceramic powder are investigated with three mechanical tests. Results obtained from diametrical, uniaxial and die compaction tests are used to fit the parameters of the Drucker/Prager-Cap plasticity model. Then these data are used to perform the simulation of the wire rolling step.
