Residual stresses in the welding joint of the nozzle-to-head area of a layered high-pressure hydrogen storage tank

In this study, a sequentially coupling finite element analysis (FEA) program was utilized to simulate the welding temperature and predict the residual stress in the weld and Heat Affect Zone (HAZ) between the nozzle and the head. The results of a numerical calculation indicated that complex residual...
