Numerical Analysis of Autofrettaged High-Pressure Aluminium Cylinder

The main objective of this research article was to investigate the influence of autofrettaged cylindrical high-pressure vessels used for abrasive jet cutting machines and to Estimate the induced residual stresses during unloading conditions using finite element analysis. Autofrettaged cylinders were subjected to hydraulic pumps to study the bursting pressure along with different orientation (0°, 30°, 60°, 90°) of crack. In addition, the strength of the vessel was determined by using Brinell’s hardness equipment along with the radial thickness of the cylinder. A numerical investigation on the autofrettaged cylinder was done by using Abaqus 6.13 with a 2D four-node bilinear solid plane element for nonlinear analysis.
