Finite element method was used to analyze the J integral evaluation method for a cylindrical specimen with deep circumferentialcrack under axial or torsional load.
通过有限元解析方法分别研究了轴向或扭转载荷下带环状裂纹圆棒试样的J积分的评价方法。

Axially symmetric longitudinal mode guided waves are more sensitive to the circumferentialcrack defects, which is basically consistent with the theoretical analysis.
轴对称的纵向模态导波对于周向裂纹缺陷较为敏感，这与模拟结果比较接近。
