Abstract

The effect of partial cracking on critical current density (J_c) has been modelled for Agsheathed superconductor tapes. Effects of crack length and density on current-voltage characteristics and J_c 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 Bi₂Sr₂Ca_n-1Cu_nO_2n+4 (BSCCO) before J_c degradation is observed. In general, a multifilament tape can withstand cracks better than a monofilament tape.
