| Abstract | ||
| Line heating is a popular technique used in the ship building and related structures that involves bending of plates using a heat source, the path of which is determined by the final shape required. Numerical techniques such as Finite Element Analysis (FEA) is popularly used to investigate the various aspects of the process that significantly reduces the time and cost involved with the experimental analyses. Based on the numerical studies, a novel strategy of heating termed here as 'pulse heating strategy' is proposed primarily for thicker plates that is expected to reduce the overall production time. Furthermore, the effect of pulse amplitude in the residual deformation of the plate subjected to line heating as per the novel heating strategy is numerically investigated in the present study. | ||
