Abstract: Components, methods for producing the components from metallic blanks, and vehicles comprising the components are provided. The components include a body having protrusions and recesses formed by a process including forming the component from a metallic blank by a drawing or stamping process. The metallic blank has at least one notch along a perimeter thereof that is configured to reduce elastic strain retained in the component formed therefrom. The at least one notch provides for relaxation of elastic strain within the component during the drawing or stamping process and thereby reduces springback distortion of the component.
