8. Process variants
Various processes derived directly from stamping are sometimes used for sheet metal working. As these techniques have been developed elsewhere
8.1 Stretch-draw
The process consists in deep-drawing the sheet metal after putting it under tensile prestress (figure 13 ). This has the advantage of reducing stress gradients in the part, thus helping to reduce the propensity for wrinkling and springback. On the other hand, local deformations in the part are significantly increased, which generally...
