| Abstract: | Based on the basic theories of mechanics, the author investigated the stress of U - shape bellows under inner pressure; summarized torsion stiffness of expansion joint, and presented expressions and curves for shearing stress distribution. Two situations of unstability were investigated,In the end, several elementary formulas were summarized based on the structure finite element analysis, providing a good theoretic platform for the further study on mechanical properties of expansion joint. |
