本文基于广泛的三维弹性有限元分析，给出了内压和面内弯曲条件下周向穿透壁裂纹弯头的弹性应力强度因子和裂纹张开位移的列表解，该分析涵盖了各种裂纹长度和弯头/管道几何形状。裂纹长度和弯头/管道的几何形状对结果的影响进行了讨论，特别强调在平面弯曲下的裂纹闭合行为。
This paper provides tabulated solutions of elastic stress intensity factors and crack opening displacements for circumferential through-wall cracked elbows under internal pressure and under in-plane bending, based on extensive three-dimensional elastic finite element analyses covering a wide range of crack lengths and elbow/pipe geometries. The effect of crack length and elbow/pipe geometry on the results is discussed, with particular emphasis on the crack closure behaviour under in-plane bending.
