    Abstract:


    In this study, Thermal Elastic Plastic Analysis (TEP) is employed to compute temperature distribution histories and distortion of a single stiffener stiffened panel caused by welding and heat straightening. An accurate gas heat source model is employed in simulating the heat straightening process. Inherent deformation is evaluated from the computed distortion of the structure. The authors compare three different gas heating methods commonly employed in actual practice and judge which is more efficient in terms of correcting welding distortion while reducing energy and time consumption.
