Investigation and Finite Element Analysis of the Welding Effects on the Buckling Behavior of Aluminum Cylindrical Shells under External Hydrostatic Pressure

In this paper, experimental of residual stress and distortion generated when welding a and numerical studies were carried out to investigate the welding effects on the buckling behavior of aluminum cylindrical shells under external hydrostatic pressure. The cylindrical shell that is made of AL 5083 was tested under hydrostatic pressure before and after it was welded. Also, the numerical study was done by finite element software code "ABAQUS". Moreover, numerical simulation based on finite element modeling was used to study the influence of welding sequences on the distribution cylindrical shell. The simulation consisted of sequentially coupled thermal and structural analyses. sequences on the d numerical results were adopted.
