Elastic deformation refers to the reversible change in shape or size of a material under the influence of an external force.
00:45
When a material is elastically deformed, it can return to its original shape and size once the force is removed.
00:52
The atomic or molecular structure of the material is temporarily distorted, but it can recover its original configuration without permanent damage.
00:59
Elastic deformation is typically characterized by a linear relationship between stress and strain.
01:06
On the other hand, plastic deformation is a permanent change in the shape or size of a material when subjected to an external force.
01:50
Unlike elastic deformation, plastic deformation involves the permanent rearrangement of atoms or molecules in the material.
01:57
The material does not return to its original shape after the force is removed.
02:00
Plastic deformation can occur when the applied stress exceeds a certain threshold known as the yield strength of the material...
