本文报告的工作目的是通过实验确定某些钢薄壳压力容器的壳-头连接应力。在研究过程中使用的头部类型为复曲面球形头部、两对一椭圆形头部、90度复曲面头部和120度复曲面锥形头部。使用的试验容器为商用容器，内部压力不超过15 psi。 调查过程中获得的信息可用于检查某些压力容器应力理论的有效性。希望它在薄壳压力容器的设计中也能被证明是有用的。

The objective of the work reported herein was to determine experimentally the shell-to-head junction stresses for certain steel thin-shell pressure vessels. The types of heads which were used during the study were a torispherical head, a two-to-one ellipsoidal head, a 90-deg toriconcial head and a 120-deg toriconical head. The test vessels which were used were commercial type vessels and the internal pressure did not exceed 15 psi. The information grained during this investigation can be used in checking the validity of certain pressure-vessel-stress theories. It is hoped that it will also prove to be useful in the design of thin-shell pressure vessels.
