Development of Computer-Aided Process Planning System for Plate Bending by Line Heating (Report 3)—Relation Between Heating Condition and Deformation

Abstract

An effective plate bending process by line heating can be achieved when the heating conditions are properly selected to produce desirable bending or inplane deformations. To make such decisions on he heating condition, the relation between heating conditions and deformations must be clarified. For his purpose, the authors studied the similarity rule which holds for the line heating process and derived wo parameters governing the deformations. Also, they developed new three-dimensional finite-element method codes as versatile tools to replace costly experiments. The validity of these codes is examined through comparison with an experiment, and they are applied to study the general relations between he parameters and the deformations of plates.
