✦ Synopsis

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

The fabrication of long silver-sheathed oxide superconducting tapes by the powder-intube technique tends to lead to non-uniformity in the core thickness during mechanical deformation and densification. This non-uniformity restricts current flow and reduces the critical current density. Using a simpl
