WebOct 6, 2024 · Deformation of solids is the term for a change in shape brought on by applying force. It is recognized that even tiny forces can result in some deformation: thus, it occurs when an external force acts on an object. The Deformation could involve crumpling, twisting, ripping, or tearing the object apart.
