Title: Energy absorbing panel structure

Abstract: Two uniform sheets are separated from each other by a corrugated member. The alternating ridges of the corrugated member are spot-welded to the inner surfaces of the two sheets. One of the sheets forms an impact receiving surface and has rows of slots, each row being located between the ridges. Upon impact, the slotted sheet is fractured and the adjoining spot-welded sections of the corrugated member are progressively deformed to distribute the impact force over a large area.
