Deformation by line heating for thin plate
초록
The line heating methods is very widely employed to correct deformation of thin plate structures. In this study, evaluation was carried out on the temperature distribution of line heating methods using FEA and practical experiments. In FEA, heat input model was established using Tsuji's double Gaussian heat input mode. This model was verified by comparing with experimental data. Thermo elasto-plastic analysis was performed using commercial FE code, MSC/MARC. Transverse shrinkage and angular distortion were measured using 3D measuring apparatus. Based on these results, a simplified analysis method is applied by using equivalent loading method.
