Plastic Deformation

02/16/26

“How do objects become permanently distorted?”

Objects may undergo reversible distortions when stretched slightly. But if the applied stress goes beyond the yield point, then the deformations will become permanent. This phenomenon, known as Plastic Deformation, is a factor that engineers must deal with in material design. Items undergoing plastic deformation will become stronger in terms of load-bearing capacity until they reach the ultimate strength, after which the item will become less strong and eventually break.
