Selection of Rubber Materials and Shapes for Energy‐Absorbing Elements
Publisher: American Society of Civil Engineers
Abstract: Energy dissipation characteristics of rubber elements are discussed as a function of material, geometry, temperature, and grouping effects. Static and dynamic energy absorption of particular rubber compounds is quantified. ...
Head Ejection during Barrier Impacts
Publisher: American Society of Civil Engineers
Abstract: During oblique vehicular impacts with longitudinal barriers, an occupant’s head is often ejected out of a side window. When this occurs, the occupant’s head can contact the barrier or an object attached thereto. This impact ...
Box-Beam Bursting Energy Absorbing Terminal
Publisher: American Society of Civil Engineers
Abstract: A new box-beam guardrail end terminal, known as the box-beam bursting energy absorbing terminal (BEAT), was designed and shown to meet current United States impact safety standards according to guidelines provided by the ...
Low‐Maintenance Rubber Crash Cushion
Publisher: American Society of Civil Engineers
Abstract: The present research was aimed at development of a low‐maintenance crash cushion utilizing reusable rubber elements. Energy dissipation characteristics of full‐scale hollow circular rubber cylinders was investigated through ...
Critical Impact Point for Longitudinal Barriers
Publisher: American Society of Civil Engineers
Abstract: A procedure for identifying critical impact points (CIP) for longitudinal barriers is presented. The procedure is based on computer simulations of longitudinal barrier impacts using the Barrier VII computer program. Critical ...
Design and Analysis of Approach Terminal Sections Using Simulation
Publisher: American Society of Civil Engineers
Abstract: Turned-down guardrail terminal sections were analyzed using LS-DYNA3D, a dynamic, nonlinear, large deformation finite-element modeling package with capabilities for simulating vehicular impacts into roadside hazards. A ...
Evaluating the Cost-Effectiveness of Roadside Culvert Treatments
Publisher: American Society of Civil Engineers
Abstract: Roadside cross-drainage culverts have been found to affect vehicle accident injury levels. As a result, highway designers have commonly used three safety treatments to protect errant motorists from striking culvert openings. ...
