Abstract
A cover covering an object includes an inner surface of the cover facing the object and spaced from the object, and an outer surface of the cover opposite the inner surface. A local energy absorber is operatively attached to the inner surface of the cover. The local energy absorber includes an energy absorbing core layer operatively attached to the inner surface of the cover and a frangible face sheet layer attached to the energy absorbing core layer facing the object. The frangible face sheet layer is to initiate fracture of the frangible face sheet layer during an impact applied to the outer surface defining an impact event having a duration of less than 20 milliseconds.
