Work Hardening Sheet Metal

Then the bending moment versus tension has been plotted.

Work hardening sheet metal. As it moves through the rollers and is compressed the metal grains are deformed. This strengthening occurs because of dislocation movements and dislocation generation within the crystal structure of the material. The model has been used to describe the effect of tension force on the bending moment in a linear elastic work hardening sheet material. Many jewelry makers have felt the effects of work hardening.

Cold rolling is the most common method of work hardening. Sometimes you can break a headpin or a piece of wire when repeatedly trying to get a coil just right. It is both a problem for and an asset to anyone who has to repair sheet metal. The answer is work hardening.

Examples of cold rolled products include steel sheets strips bars and rods. The breakage is not due to bad metal sheet it has just been work hardened by too much movement. The asset is that the areas where dies have deformed sheet metal from its original flat state provide much of the necessary panel strength in body design. Many non brittle metals with a reasonably high melting.

Although the first few deformations imposed on metal by such treatment weaken it its strength is increased by continued deformations. Work hardening also known as strain hardening is the strengthening of a metal or polymer by plastic deformation work hardening may be desirable undesirable or inconsequential depending on the context.
