Definition
- Noun:
- The act or process of deforming; the state of being deformed: The action of twisting, bending, or otherwise changing the shape of something, or the resulting condition.
- An alteration in the shape or dimensions of an object due to stress: A physical change in an object's form caused by applied forces, such as pressure, tension, or shear.
- A change for the worse; a disfigurement or distortion: A negative change in form, appearance, or character.
Examples of Usage
- Noun:
- The plastic deformation of the metal occurred under extreme pressure. (A permanent change in the metal's shape happened due to force.)
- Geologists study the deformation of rock layers over millions of years. (They study how rock layers change shape over time.)
- The scandal caused a deformation of his public reputation. (The scandal resulted in a damaging change to his public image.)
Advanced Usage
- Elastic deformation: A temporary change in shape where the material returns to its original form after the stress is removed.
- The spring exhibits elastic deformation when stretched.
- Plastic deformation: A permanent change in shape where the material does not return to its original form after the stress is removed.
- Bending a paperclip causes plastic deformation.
- Shear deformation: A change in shape caused by forces sliding parts of the object parallel to each other.
- Shear deformation is common in geological faults.
Variants and Related Words
- Deform (verb): To change or spoil the usual or natural shape of something.
- Heat can deform plastic.
- Deformity (noun): A condition of being badly shaped or formed, often used in a medical context.
- The condition can cause bone deformities.
Synonyms
- Distortion: The action of twisting or altering something out of its true, natural, or original state.
- Contortion: A twisted or bent state, often implying a complex or unnatural shape.
- Warping: The process of becoming bent or twisted out of shape, typically as a result of heat or dampness.
Related Phrases
- Deformation field (technical): A mathematical description of how every point in a body moves when it is deformed.

- Deformation retract (mathematics/topology): A continuous transformation that shrinks a space into a subset of itself.
