Abstract
The selection of the optimum expansion joint depends on a technical as well as an economical aspect. The bellows is the basic element of expansion joints. The aim of this research is to perform a Finite Element Analysis (FEA) of metal bellows to investigate its static behavior and validate it with Expansion Joints Manufacturing Association (EJMA) standard. Further a parametric study is used to investigate the meridional stress component on the metal bellows at various temperatures. The result explains that the dimensions of convolution curvature are sensitive to its mechanical behavior. Also the component becomes flexible and peak stresses are reduced at elevated temperature.
