Abstract: The effectiveness of roadside safety appurtenances under impact with minisized automobiles is investigated. The vast majority of existing roadside hardware have been qualified under guidelines which have not considered ...

Abstract: This paper presents the results of finite element computer simulations of vehicular impacts with a roadside crash cushion. DYNA3D is used to model the energy-dissipating response of the Narrow Connecticut Impact Attenuation ...

Abstract: A three‐stage analytical model for predicting the final midpoint deflections of viscoplastic, clamped beams under impact loading conditions is presented. The model includes traveling plastic hinges and accounts for strain ...

Abstract: Each year approximately 160,000 people are involved in accidents where the side of a vehicle strikes a fixed‐roadside object such as a tree, utility pole, or guardrail. Of these 160,000 occupants, 60,000 are injured and ...

Abstract: The energy dissipation characteristics of steel tube clusters are investigated with a view toward using such a system as a stationary energy absorbing device. Experiments performed on small scale models made up by connecting ...
