Buckles caused by impact create additional work hardening in an automotive sheet metal panel, but bent metal is not necessarily buckled metal.

Question

Quizplus · Accepted Answer

Buckles caused by impact indeed create additional work hardening due to the deformation process, which alters the metal's structure making it harder. However, bending metal, such as in a controlled manufacturing process, does not necessarily lead to buckling, which is a specific type of deformation characterized by a sudden failure mode in structural elements.
