Abstract (en)

[origin: US5519934A] Method for the local forming of material tending towards brittle fracture, such as certain aluminum alloys, in which during the forming tensile loads are exerted on the material, such as for example in joggle joining. Brittle fracture is avoided if the material is subjected to a pressure load in the region which is to be formed.
