Analysis of the Bending Strain Influence on the Current-Voltage Characteristics of HTC Superconducting Tapes

Abstract

Analysis of the influence of the bending strain on the electric properties of the HTc superconducting tapes is presented. The results of experimental investigations in liquid nitrogen temperature of the current-voltage characteristics and critical current of Bi-based tape are given for various bending strain values. Theoretical model of obtained dependences is proposed, while results of numerical calculations are in qualitative agreement with experimental data.
