Based on the line-spring shell model, J integral of circumferential and axial cracks in pipe elbows is calculated by EPRI method. Then by following the procedure of EPRI, F 1 function and h 1 function are given.

采用线弹簧壳体模型进行有限元计算求解含裂纹弯管的J积分，而后仿照EPRI方法的思路，给出了J估算式及其相关系数F1和h1。

On h Convex Function

h凸函数

For circumferential crack case, it has been found that the better h 1 function can be gotten by using EPRI method if two methods ( EPRI and NSC) for determining M 0 are used.

对于含周向裂纹情况，采用两种M0的计算方法（EPRI方法和净截面法NSC）所得到的h1值相比较发现，EPRI公式得到了较好的h1函数分布。

It can be find that the solution using the H function is superior to the solution using the G function ( generalized Green's function).

文中给出三个命题，由此可以看出，用H-函数比用G-函数（一般的格林函数）解此边值问题更为优越。
