本文基于Bean模型，对无限长圆柱形高温超导体（HTS）边缘贯穿裂纹周围的电流分布进行了实验和分析研究。通过一个简单的保角变换，得到了无变形高温超导体中裂纹周围的电流分布。结果表明，电流在裂纹尖端是奇异的。引入电流强度因子来表征奇异性，其阶数等于-1。此外，根据裂纹周围的陷阱场分布进行了实验验证，实验结果与理论分析相差不大。
This paper presents experimental and analytical investigations into the distribution of current around a through-edge crack located in an infinitely long cylindrical high temperature superconductor (HTS) on the basis of the Bean model. Current distributions around the crack in the HTS without deformation are obtained by a simple conformal mapping. It is shown that the current is singular at the tip of the crack. An intensity factor of the current is introduced to characterize the singularity, the order of which is equal to −1. Additionally, an experimental verification according to the trapped field distributions around the crack is carried out, and the experimental results show little difference with the theoretical analysis.
