STRETCH FORMING: is the forming of sheet, bars, and rolled or extruded sections
over a form block of the required shape while the workpiece is held in
tension. The work metal is often stretched just beyond its yield point
(generally 2 to 4% total elongation) to retain permanently the contour
of the form block.
