Residual Stress Relaxation of DRWDs in OSDs under Constant/Variable Amplitude Cyclic Loading
Applied Sciences, 2020 An orthotropic steel deck (OSD) has a complicated structure, and its fatigue life is mainly determined by various welding details. Fatigue assessment of deck-to-rib welding details (DRWDs) under long-term train loads is an important concern for engineers.

Effect of Transverse Restraint on Welding Residual Stress in V-Groove Butt Welding
Metals, 2022 When evaluating the safety of steel structures, welding residual stress is used as the secondary load and if there is any restraint, the yield stress of the base material is used for secondary load, regardless of the size of the restraint.

Research on the residual stress distribution of aircraft engine blades repaired by laser shock peening and laser cladding composite process [PDF]
MATEC Web of ConferencesThe traditional laser cladding (LC) repair process for aircraft blades introduces residual tensile stress near the heat affected zone, which causes a decrease in the strength of the joint interface of the repaired part.
