Answer:
Elastic Deformation:
- Elastic deformation is due to the elasticity of the body i.e., the deformation disappears on removal of external forces and the lattice regain its original structure.
- This type of deformation is temporary in nature.
- This type of deformation depends mainly on the chemical bonding of the substance.
- It occurs due to bending or stretching of chemical bond under applied stress where atoms do not slip pass over each other.
- It is a reversible process.
Plastic Deformation:
- Plastic deformation is due to the plasticity of the body i,e., the structure can be easily shaped or molded .
- This type of deformation is permanent in nature.
- This type of deformation occurs mainly due to breakage of chemical bonds(limited in number) between constituent atoms.
- Atoms may slip pass each other causing dislocation of atoms , resulting in permanent deformation even after stress is removed.
- It is an irreversible process.
