| Abstract: | In this paper, a 3-D parametric finite element model for a pressurized cylinder with a longrectangular tube was established using the finite element software FEPG. Stress distribution in the structure underan internal pressure was obtained. It was found that the largest stress intensity was located at the connection of thecylinder and the tube in tube corner area. For the long rectangular tube, it was not effective to reduce theconcentrated stress intensity by increasing the thickness of the cylinder or the tube. Strength reinforcementstructures were proposed and all the strength criteria were finally satisfied. |
