PRESS-MOLDED ARTICLE AND METHOD FOR DESIGNING SAME

摘要

This press-molded article is molded by press working from a tailored blank obtained by butt-welding a plurality of metal sheets. The press-molded article includes a flange section (10b), and an arc-shaped region (14) which is a portion of the region of the flange section (10b) that is formed by stretch flange deformation and has an open inner peripheral edge (14b). A welding line (L) of the tailored blank intersects with the inner peripheral edge (14b) and an outer peripheral edge (14a) of the arc-shaped region (14). An angle θ between the welding line (L) and the maximum principal strain direction of the stretch flange deformation is 17-84°.
