Abstract Demands for lightweighting and crashworthiness of the vehicle body have increased. For this purpose, advanced high strength steel to automobile was regarded as a solution with respect manufacturing cost impact energy absorption. However, increasing automotive sheet lead diversity problems caused by tool wear due higher forming load than that commonly used sheets. Hence, systematic expe...

In the realm of van design, researchers have been diligently working to enhance rollover crashworthiness while concurrently achieving lightweight body structures. Unlike front and side impacts, is impacted by a greater number structural dimensions material parameters. As such, this paper implements an unreplicated saturated factorial design conduct factor screening for vehicle crashworthiness. ...

Hybrid structures have the advantage of combining different types materials at same time. The trend lightweight design in transportation industry has promoted development and application composite with good crashworthiness performance. Low-density crushable foam-filled metal-composite hybrid potential advantages as energy-absorbing components. This study investigated mechanical characteristics ...

Due to their superior structural and mechanical properties, materials with negative Poisson’s ratio are of increasing interest research scholars, especially in fuel-efficient vehicles. In this work, a new concave I-shaped honeycomb structure is established by integrating the re-entrant hexagon beam structure, its characteristics energy absorption properties investigated. The effect parameters o...

A hardness-based model for tailor hardened boron steel is presented that takes into account the softened heat-affected zone of resistance spot welds. The computational model is designed for crashworthiness simulation of fully and partially hardened components obtained by tailored tooling. Five different hardness grades of 22MnB5 are used for model calibration. The proposed model is validated wi...

Mass transportation systems and specifically bus systems are a key element of the national transportation network. Buses are one of the safest forms of transportation. Nonetheless, bus crashes resulting in occupant injuries and fatalities do occur. Therefore, crashworthiness research is a continuing effort. Using funding from the Federal Transit Administration, NIAR at Wichita State University ...

In Europe, emphasis is being transferred from injury prevention to accident prevention to reduce road casualties. This study attempted to identify the current potential for serious casualty reduction using passive safety by examining the crash performance of new cars with seriously injured occupants. The Co-operative Crash Injury Study conducts in-depth investigations of around 1200 vehicles pe...

The response surface methodology (RSM), which typically uses quadratic polynomials, is predominantly used for metamodeling in crashworthiness optimization because of the high computational cost of vehicle crash simulations. Research shows, however, that RSM may not be suitable for modeling highly nonlinear responses that can often be found in impact related problems, especially when using limit...

With an increasing number of and also more complex demandson today’s automobiles the need for fast and accuratesimulations to support the Engineering Design (ED) process isgetting more important. The demands that are put on theautomotive designs are often contradictory i.e. weight againststiffness, and no one optimal set of solutions can be found,rather a trade-off s...

SOLAS2020 damage stability regulations are based on probabilistic distributions. Those originate from the pooled analysis of collision accidents across a fleet with bias towards cargo ships. This paper introduces method that accounts for collision-based crashworthiness ship The reshapes statistical SOLAS distributions given or structural details reference section and her reinforced version.
