Quizplus · Accepted Answer

Plastic deformation refers to a permanent change in shape or structure of a material caused by external forces, such as stretching or compressing. Once plastic deformation occurs, the material will not return to its original state even when the force is removed. This is different from elastic deformation, where the material returns to its original shape after the force is removed. Clay is a material that is prone to plastic deformation. Brittle deformation refers to the breaking or fracturing of a material under stress.
