What are the characteristics between elastic deformation and plastic deformation?


Elastic deformation: deformation of the material under the action of external force, when the external force is canceled, the material can disappear and can completely restore the original shape of the shape of the known elasticity. This recoverable deformation is called elastic deformation. An important feature of elastic deformation is its reversibility, that is deformed by the force, after the removal of the load, the deformation disappears. This reflects the essential phenomenon that the elastic deformation depends on the binding force between atoms. Atoms in the equilibrium position, the atomic spacing of r. , The potential energy U is in the lowest position and the interaction force is zero, which is the most stable state. When the atomic force will deviate from its equilibrium position, the atomic spacing will increase when the gravitational attraction; atomic distance will produce repulsive force. In this way, the removal of external forces, the atom will return to its original position, the resulting deformation will disappear, which is elastic deformation.


Plastic deformation: It is a physical phenomenon that a substance-including fluid and solid under certain conditions, deforms under the action of external force and can not be restored to its original shape when the applied external force is removed or disappeared.
