Energy-absorbing corrugated metal highway buffer. Paper presented at the 52nd Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1973.

Scale-modeling techniques employed to develop and test an energy-absorbing barrier or crash cushion composed of a family of parabolic corrugated-metal arches oriented parallel to the roadway surface to form a guardrail for glancing side impacts and to deform plastically to absorb the energy of a vehicle impacting into the nose, are described.
