Energy-dissipation characteristics of steel tubes

This paper presents the results of an experimental investigation of the energy-dissipation characteristics of steel tubes subjected to large deformations under both quasistatic and impact diametrical loading conditions. Recently, such structural elements have been employed in the design of several impact attenuation systems used in highway-safety applications. The importance of considering the effects of different boundary conditions, strain-rate effects, and the influence of inertia in predicting the response of such systems is demonstrated. Under impact conditions it is shown that a cluster of such tubes is subjected to a shock wave which travels through the system. These experimental results compare favorably with numerical-structural shock-wave-theory predictions.
