Background/Objectives: The experimental investigation and analysis were carried on metal bellows made of 304 stainless steel tubes. Methods/Statistical analysis: FEM analysis using ANSYS was done by varying the manufacturing parameters of bellows, such as internal pressure and die stroke to get an optimum crown diameter of the bellows. Findings: An experimental investigation in the form of an optimization is done by varying the manufacturing parameters of metal bellows. Improvements/Applications: Hardness test, forming height vs thickness distribution and micro structure analysis were done to study the hydroforming process.

This paper addressed the modeling and optimization of loading path in T-shape hydroforming of tubes using Simulated Annealing (SA) algorithm. Analysis of variance shows that some of pre-selected parameters in loading paths have not significant effect on the deformed tube. Hence, some of optimized parameters found initially, are replaced with their own fixed optimum values in order to seek for the other parameters in more detail by the Simulated Annealing (SA) algorithm. According to the intensity of effectiveness on the deformation, six more important parameters are chosen and their minimum and maximum limitation values are determined. In this case, sixty four different tests for different loading paths are designed by Design of Experiment (DOE) and full factorial method. By using mathematical modeling all required loading parameters are obtained. Proposed models of formability embedded into Simulated Annealing algorithm and optimum value for loading parameters and optimal load paths are found. The obtained results show that more accurate loading path may be found for T-shape of tube hydroforming.
