The most characteristic work in shipbuilding industry is to bend thick-steel plate. It is often said that plate bending technique is one of the most difficult ones. In order to solve those problems, a lot of investigations were conducted in the past. The preceding paper suggested one means of solutions. That reported the necessity of development of a simulator for plate bending by Line-Heating. The simulator system was based on a simplified non-linear elastic plate bending model instead of thermal elasto-plastic and large deformation analysis. But the system left much room for improvement. The aim of this supplementary paper is to introduce in-plane shrinkage, to select best restraint conditions in FEM numerical calculation, and to construct much better interface. Then users can understand plate bending intuitively and acquire know-how of it. The simulator is useful to a training facility for technicians.
