| Abstract: | The stress distribtions in a thick walled pressure vessles were obtained by three dimensional finite element analysis. The influences of different welded structures on the stress distributions were studied, and the loading capability of the pressure vessels with various welded structures were compared. In this research, automatic division of three dimensional mesh was accomplished by mapping and Autolisp programming. The research results will be helpful for the selection of welded struture in the production of pressure vessels. |
