A vehicle hood assembly includes a first panel member, a second panel member, and a third panel member disposed between the first panel member and the second panel member. The third panel member includes a corrugated body. The third panel member defines a plurality of panel perforations extending through the corrugated body in order to attenuate kinetic energy imparted to the hood assembly.
