在对球冠线裂纹分析的基础上，本文给出了含轴向裂纹圆柱壳的应力。裂纹问题所特有的应力的平方根反比奇异性行为，得到在拉伸和弯曲分量。这个奇异性可能与在初始平板中发现的奇异性有关，其中括号中的量是正的。基于Griffith理论，推导了一个近似的断裂准则，给出了这种情况下的弯拉干涉曲线。
Following an earlier analysis of a line crack in a spherical cap, the stresses in a cylindrical shell containing an axial crack are presented. The inverse square root singular behavior of the stresses peculiar to crack problems is obtained in both the extensional and bending components. This singularity may be related to that found in an initially flat plate bywhere the quantity in parentheses is positive. An approximate fracture criterion, based on Griffith's Theory, is also deduced, and bending-stretching interaction curves for this case are presented.
