| Research Abstract |
The objective of this research is the development of the method to form the curved surface by pressing for the ship-building.
It is necessary to select the appropriate pressing conditions to form the objective shape by pressing. Therefore, the database of inherent deformation and angular distortion is created by using the press analysis tools developed. On the other hand, the heating and correcting conditions of line heating is calculated from the database of the objective inherent strain distribution as the pressing. To verify this method, a series of the thermal-elastic-plastic finite element analysis, which is one of strongly non-liner analyses, is performed and the result is that the required curved shape is obtained with three times correcting heating.
