Buckling mode shapes in incremental forming of sheet metal
A common technology for manufacturing of large-scale vessel-ends is incremental forming. The first step in forming process is based on buckling phenomena. The buckling mode shapes of circular plate influence wrinkling and surface quality of final product. Increased number of wrinkles in the first forming step lengthens the manufacturing process and increases the number of forming steps needed. To obtain the desired buckling mode shape, an analysis was performed by varying tool parameters. The analysis resulted in defined relationship between tool parameters and buckling mode shapes, and guidelines for the tool design in terms of minimum wrinkling.
