Lightweight structures: An innovative method to uniform the thickness of metal sheets by patchwork blanks

Metal sheet forming is widely used in industrial field. Generally, the use of patchwork banks allows the manufacturing of a more uniform thickness of the formed parts. Often, they are obtained using welding techniques: in these cases, distortions and localized metallurgical transformations could hav...
