...Yu-Ping Yang; T. D. Huang; Steve Scholler; Randy Dull; Charles R. Fisher; Wei Zhang Weld residual stresses on ship structures were significantly investigated by using a three-step approach. Step 1 is to measure residual stress on small samples in laboratories to validate measurement methods, step 2...

..., residual stresses and distortions occur in the welded components. These distortions are introduce in the block assembly process in shipbuilding. These unwanted distortions result in additional production cost because necessary rectification process and extra manpower are required. These also cause delays...

... at the joint. During and after welding, the surrounding deck material around the tie-downs must deform elastically to preserve dimensional continuity, creating residual stresses. Weld-induced residual stress is a major concern because the tie-downs are subject to cyclic, dynamic loading which could induce...

... et al. 2013a; Mandal et al. 2015). The nonuniform expansion and contraction of the weld metal and the surrounding parent metal induces distortions and residual stresses in the material. Because of this, the dimensional accuracy and the structural integrity of the welded structures are affected...
