摘　　要： 采用作者等先前提出的J-积分的半经验公式进行理论计算和预测，探讨了高温环境中受弯曲载荷作用下构件的三维半椭圆表面疲劳裂纹的贯穿举动，分析了表面裂纹与背面裂纹的合体规律，并进行了实验验证． The pass - through propagation patterns of 3 - dimensional semi-elliptical surface fatigue crack under bending loads in high temperature, and then the connection patterns of an inside surface crack and an outside surface crack were discussed An empirical J-integral equation proposed by author was used for the analyses and prediction of the propagation patterns of the surface cracks. The experimental studies for the surface crack propagation were also performed.
