Abstract

The effect of partial cracking on critical current density (Jc) has been modelled for Agsheathed superconductor tapes. Effects of crack length and density on current-voltage characteristics and Jc were evaluated for monofilament and multifilament tapes. The results show that a single long crack is more harmful than numerous small cracks. Multiple small partial cracks (less than 20% of core dimension) can be present in the Bi2Sr2Can-1CunO2n+4 (BSCCO) before Jc degradation is observed. In general, a multifilament tape can withstand cracks better than a monofilament tape.
