Deformation of Metals

Deformation is the change in dimension or forms of matter under the action of the applied forces. Deformation is caused either by the mechanical action of the external forces or by various physical and physio-chemical processes. Deformation may be permanent or temporary depending upon the type of deformation whether it is plastic or elastic. So metal deformation are of following two types:  (a)      Elastic deformation  (b)      Plastic deformation Elastic Deformation – The deformation is called elastic if the strain or deformation produced in the material corresponding to a given stress completely…
