本公告介绍了一项分析和实验研究计划的结果，该计划旨在提供确定承受各种形式外部载荷的圆柱形和球形压力容器接管连接中局部应力的方法。当喷嘴位于封头的球形区域时，也可以得到椭圆和复曲面球壳的解；对于椭圆封头，可使用等效的冠半径。该公告基于P.P.Bijlaard在20世纪50年代和60年代初所做的工作，涵盖了符号约定、参数、应力计算、无量纲曲线、球壳和圆柱壳的应用限制，以及球壳最大应力的简化计算。 WRC 107程序仅提供壳体中的应力计算，不计算喷嘴应力。对于某些壳体和喷嘴配置，这可能会导致不保守的结果。

The Bulletin presents the results of an analytical and experimental research program aimed at providing methods for determining localized stresses in cylindrical and spherical pressure vessel nozzle connections subjected to various forms of external loadings. Solutions for elliptical and torispherical shells may also be obtained in the nozzle is in the spherical region of the head; for an elliptical head an equivalent crown radius may be used. Based on the work of P.P. Bijlaard performed in the 1950's and early 1960's, the Bulletin covers the sign conventions, parameters, calculation of stresses, nondimensional curves, and limitations on application for spherical and cylindrical shells and an abridged calculation for maximum stress in spherical shells. The WRC 107 procedure only provides stress computation in the shell, nozzle stress are not computed. This may lead to unconservative results for some shell and nozzle configurations.
