Definition, Meaning & Synonyms
plastic deformation
noun
/ˈplæs.tɪk diˌfɔːrˈmeɪ.ʃən/
Definition
A permanent change in shape or size of a material when subjected to stress, beyond its elastic limit.
Examples
- When metal is bent beyond its yield strength, it undergoes plastic deformation.
- The plastic deformation of the clay made it easy to mold into various shapes.
- Engineers must consider plastic deformation in the design of structures to ensure they can withstand forces without permanent damage.
Meaning
Plastic deformation occurs when the applied stress exceeds the elastic limit of a material, leading to a permanent change that cannot be reversed.
Synonyms
- Permanent deformation
- Irreversible change
- Yielding
