Abstract: Braced metallic tubes are used to dissipate kinetic energy in impact attenuation devices used in transportation safety applications. It is an experimentally observed fact that these braced tubes collapse asymmetrically, ...

Abstract: Side‐impact collisions with roadside objects, such as trees, luminaires, signs, and guardrails, a serious type of accident, have not been adequately addressed by the roadside hardware testing community due to the difficulties ...

Abstract: A relatively simple approach is first presented for the approximate analysis of the collapse of circular rings under external pressure. It accounts for geometrical and material nonlinearities, and is able to approximate ...

Abstract: Vehicles that run off the road and then slide sideways into fixed objects along the roadside are an important accident scenario that has been often overlooked in developing roadside hardware. This paper combines the results ...
