Deformations of metals

Designing is one of the basic technological properties of metallic materials. Design is defined as the ratio of maximum deformation that the material can handle (without the occurrence of crack or fracture) and process parameters. In metal forming deformation of the work piece is done in one or more steps, where the most commonly used tool consists two main parts. Molding machines have the task of guiding tools and some parts of the tool can be caught in the work piece to provide the necessary forces, torques or working deformation.
