Résumé

In order to feed a new mechanical model of the Powder In Tube (PIT) processing BSCCO/Ag conductors, a plastically compressible constitutive model of the powder is proposed and its parameters measured. We use a simple compressible model of the CAM-CLAY type with work hardening and softening depending on density variation. The unknown parameters of the model, the plastic properties of ceramic filaments, were evaluated from experimental studies of the real BSCCO powder by estimating the yield surface at a given density.
