The most characteristic work in shipbuilding industry is to bend thick-steel plates. It is often said that plate bending technique is one of the most difficult one. In order to solve those technological problems, a lot of investigations were conducted in the past 30 years in Japan. A series of universal press with multiple piston heads have been studied, in order to automate plate bending process. The other approach was contributed by 4th Subcommittee of the Systems Technology and Computer Application Committee. They proposed that such shipbuilding skills should systematically be analysed to be applicable for researches on Artificial Intelligence and Expert System. The aim of this paper in to develop a simulator for plate bending by Line-Heating. A Simplified non-linear elastic plate bending model is introduced instead of thermal elasto-plastic and large deformation analysis. Engineering work station is used in the main system and FEA is carried out in numerical calculation. And the system supports good interface. So user can understand plate bending intuitively and acquire know-how of it. The simulator is useful to a training facility for technicians.
