This research deals with axial and oblique impact crash tests on simple and hybrid composite tubes. Axial and oblique impact tests have been generated on simple and hybrid composite tubes with one, two and three layers. A drop test rig was used to conduct the experiments. Furthermore, in order to gain more detailed knowledge about the crash process, finite element simulations of the experim...

Significant trends in the vehicle industry are autonomous driving, micromobility, electrification and increased use of shared mobility solutions. These new automation classes lead to a larger number occupant positions, interiors load directions. As safety systems interact with protect occupants, it is essential place human, its variability vulnerability, at center design operation these systems...

We study a rational expectation model of bubbles and crashes. The model has two components : (1) our key assumption is that a crash may be caused by local self-reinforcing imitation between noise traders. If the tendency for noise traders to imitate their nearest neighbors increases up to a certain point called the \critical" point, all noise traders may place the same order (sell) at the same ...

background: motor vehicle crashes (mvc) are considered to be the most common safety challenge, causing more than a million deaths worldwide annually. objectives: the current study was aimed at identifying the etiological role of human and vehicle safety factors in road crashes, and their effects on the severity of injury and fatality in the sistan and baluchistan province, south east iran. pati...

INTRODUCTION Finite element models of cervical spines are used to simulate loading response and predict injury in car crash scenarios. A computational model of the cervical spine has been developed using new ligament material data including strain rate effects. Model validation is an important requirement and must be conducted at appropriate strain rates for accurate prediction of kinetic and k...

The objective of this study was to verify and validate an enhanced cervical spine segment finite element model to predict tissue-level failure under tension and compression loading. The predicted failure locations were representative of reported cervical spine injuries, and the predicted peak failure forces were within the reported experimental corridors. The displacement to failure of the tens...

The Transportation Research Forum, founded in 1958, is an independent, nonprofit organization of transportation professionals who conduct, use, and benefit from research. Its purpose is to provide an impartial meeting ground for carriers, shippers, government officials, consultants, university researchers, suppliers, and others seeking exchange of information and ideas related to both passenger...

As the automotive industry moves towards autonomous driving, it becomes increasingly necessary to develop advanced collision avoidance systems, crash prediction systems, and the tools for their rigorous analysis. Probabilistic traffic models, providing a statistical representation of the future behavior of traffic participants, are crucial for risk estimation in automotive collision avoidance s...

A critical part of any risk assessment is identifying how to represent exposure to the risk involved. Recent research shows that the relationship between crash count and traffic volume is non-linear; consequently, a simple crash rate computed as the ratio of crash count to volume is not proper for comparing the safety of sites with different traffic volumes. To solve this problem, we describe a...
