  1. Plastic deformation definition: Plastic deformation in the broadest sense means permanent deformation in the absence of external constraints (forces, displacements).
  2. From an atomic perspective, plastic deformation corresponds to the breaking of bonds with original atom neighbors and then reforming bonds with new neighbors as large numbers of atoms or molecules move relative to one another; upon removal of the stress they do not return to their original positions.
  3. Plastic deformation fracture: For most metallic materials, elastic deformation persists only to strains of about 0.005. As the material is deformed beyond this point, the stress is no longer proportional to strain (Hooke’s law) and permanent/nonrecoverable/plastic deformation occurs.
  4. The transition from elastic to plastic is a gradual one for most metals; some curvature results at the onset of plastic deformation, which increases more rapidly with rising stress..
  5. The mechanism of plastic deformation is not the same for all classes of materials and it is necessary to consider the various materials groups separately.
  6. Plastic deformation metal: Metals, in general, are characterized by possessing high elastic modulus values, and also the ability to be strained m a plastic manner.
  7. Plastic deformation of polymers: Some metals will begin to deform plastically at very low values of stress and will yield to a very considerable extent before fracture occurs. Other metals and alloys show little plastic yielding before fracture. These latter materials are termed brittle.
