What is plastic deformation?
Deformation
Definition and scope of the subject
Elastic deformation
Plastic deformation √
Metal forming - a metal working process in which the shape of a workpiece is altered to the required shape by plastic deformation without material removal.
Plasticity – the material’s ability of being permanently shaped or formed without fracture .

Plastic forming theory
1) What metal forming technology can do for us ?
2) Why metals can be plastically deformed ? (physical metallurgy)
3) How metals deform under applied load or how load is applied to obtain a required part shape? (theory of plasticity)
The study of Plastic Forming Theory to find answers to the following questions:
