Abstract
A vehicle hood covering an underhood object includes an inner surface of the vehicle hood facing the underhood object and spaced from the underhood object, and an outer surface of the vehicle hood opposite the inner surface. A local energy absorber is operatively attached to the inner surface of the vehicle hood. The local energy absorber is a multiply-connected structure. The local energy absorber includes a wall defining an interior surface having symmetry about a central plane normal to the inner surface of the vehicle hood. A plurality of apertures is defined in the wall symmetrically about the central plane to initiate buckling and fracture in the wall during an impact applied to the outer surface defining an impact event having a duration of less than 20 milliseconds.
