Elastic-Plastic Analysis and Experiment on the Expanded Joints of Aluminium Tubes to Steel Tube-Sheets

The joint difficulty of aluminium tubes and steel tube-sheets was solved by using thin-wall steel casings in aluminium tubes, and expanding and connecting the thin-wall steel casings to steel tube-sheets, a theoretical analysis and pulling out strength test were conducted by using elastic-plastic theory for the expanding structure. The result shows that the pulling out strength of the expanded joints was excellent and could satisfy the demands of manufacturing businesses.
