Plastic deformation

Plastic deformation refers to the permanent change in shape or size of a material when it is subjected to stress beyond its elastic limit. Unlike elastic deformation, where a material returns to its original shape after the stress is removed, plastic deformation results in lasting alterations. This occurs in many materials, such as metals, when stretched or compressed. It allows for processes like metal forging and shaping, where materials are intentionally deformed to create desired forms or products. Overall, plastic deformation is a crucial concept in fields like engineering and materials science.
