Notes:
Welding residual plastic strains and residual stresses are the product of complicatednonlinear behaviors of the structures during welding. The residual strains and stresses for stiffenedstainless steel structure and welding fatigue analysis are studied in this paper. Thethree-dimensional transient temperature field is analyzed by FEM first. Doing the weldingexperiment for fundamental model is to verify the numerical results, the infrared thermograph isused to follow and record the whole process. The results of FEM are supported by experimentaldata. Then, the elastic-plastic-model is established to analyze the residual strains and stresses.Based on the stresses, loading and fatigue factors, according to Miner fatigue damage law, somefatigue behaviors such as fatigue life and remaining life are obtained
