ABSTRACT:
Disclosed is a curved surface forming method for a metal plate. Nonlinear finite element analysis of elasto-plastic large deformation is performed on the metal plate. The metal plate to be worked is formed so as to have a three-dimensional target curved surface on the basis of the analysis results using a plurality of forming punches connected to a hydraulic apparatus. The curved surface formation method is very useful when the metal plate is worked for small quantity batch production.
