METHOD FOR PREDICTING METAL PLATE SHAPE AND METHOD FOR MANUFACTURING METAL PLATE

To accurately predict a metal plate shape.SOLUTION: A method for predicting a metal plate shape determines a waveform profile by buckling analysis using an elastic strain difference existing inside the metal plate even after buckling, when the waveform after buckling is predicted based on a plastic...
