Thick-walled cylinders are widely used as compressor cylinders, pump cylinders, high pressure tubing, process reactors and vessels, nuclear reactors, isostatic vessels and gun barrels. In practice, cylinders are generally subjected to sudden and frequently drastic pressure fluctuations, necessitating enhanced strength of such cylinders. A process for enhancing the strength of thick-walled cylinders is referred to as "autofrettage", which extends the service life of the cylinder. This research work deals with the hydraulic and mechanical autofrettage of metal tubes with the objective to attain enhanced strength. Five metal tubes are randomly selected for analysis. Experimental data is obtained to analyze the behavior of different parameters used during, before, and after the autofrettage process, specifically considering two-stage autofrettage. The modeling of the metal tube is carried out in WildFire - ProEngineering, while the analysis employs finite element software ANSYS and COSMOS. The graphical analysis of swage autofrettage is executed using MATLAB. Results are validated using available experimental and numerical data.
