Deformation
Deformation refers to the change in shape or size of a material or object when subjected to an external force or stress. This can occur elastically, where the material temporarily changes shape and returns to its original form once the force is removed, or plastically, where the change is permanent. Deformations help us understand how materials respond under different conditions, such as bending, stretching, or compressing, and are vital in engineering and construction to ensure structural safety and durability.
