Description

High temperature superconducting tapes are subject to periodic stresses and strains during AC applications, which may cause performance degradation of HTS tapes. In response to this problem, we built a periodic stress fatigue test platform for HTS tapes, and tested the critical current degradation characteristics of YBCO tapes with two different stabilizing layers under periodic stress. The causes of the critical current degradation of YBCO tape are analyzed. The effect of stabilizing layer materials on the fatigue properties of YBCO tapes are also discussed.
