Springback is generally referred to as the change of part shape that occurs upon removal of constraints after forming.
In many cases, such geometric change is undesirable as the final obtained part shape geometry deviates from the desired tooling geometry. Therefore, often people use “shape distortion” to describe springback. It is closely related to dimensional control for sheet metal parts.
