Effect Of Bending On J(C)-Epsilon Characteristic Of Silver-Sheathed Oxide Superconducting Tape With Sausaging

Sausaging in the core of silver-sheathed powder-in-tube generated superconducting tapes restricts current flow and lowers the effective critical current density J(c). Although generally detrimental, such sausaging may indeed (a) enhance the J(c) tolerance to bending strain epsilon relative to the zero-strain J(c); and (b) be partially responsible for the irreversibility limit observed in the J(c)-epsilon dependence. Using a simple model, the effects of sausaging on the J(c)-epsilon characteristic are qualitatively investigated.
