Security assessment of over roundness circumferential weld of the pressure vessel

3D Finite Element Analysis of Transverse Welding Joint in Aluminum Alloy During Billet-to-billet Extrusion Process

In the consideration of circumferential weld imperfection,a great amount of nonlinear numerical analyses are conducted to investigate the stability of the cylindrical shells when the cylinders are subjected to partial axial compression with the loading subtended angle being less than 10°.
