Trans. Nonferrous Met. Soc. China 24(2014) 657-664 Effect of welding sequence on residual stress in thin-walled octagonal pipe-plate structure Ding-fa FU1, Chang-qing ZHOU1, Can LI1, Guan WANG2, Luo... on welding residual stress distribution in a thin-walled 6061 aluminum alloy structure. To obtain sound numerical results, the thermo-mechanical behaviour was simulated using a direct-coupled......
thickness crack was analyzed using SINTAP procedure and FEA incorporating weld induced residual stresses. Weld induced longitudinal residual stress profile can be obtained through SINTAP procedure, FEA or experimental analysis. This residual stress profile can be fitted with the trapezoidal residual stress profile available in SINTAP. For three different cases, crack length and residual stress......
