The Biomechanics of the Perinatal, Neonatal and Pediatric Cervical Spine: Investigation of the Tensile, Bending and Viscoelastic Response
… vehicle crash related. Current progress in child occupant protection, including increased and proper restraint usage continues to reduce serious injury and fatalities to child occupants. However, improper restraint usage and incorrect child seating location, especially with children transitioning …

Submarining and Abdominal Injury for Rear-Seated Mid-Size Males during Frontal Crashes
… compared to the front seat for all restrained occupants; however, studies have found that the front seat in newer vehicles might be safer for older adults than the rear seat. While adults make up only 19% of rear seat occupants in frontal crashes, they make up 48% of fatalities (Tatem and …

Wind-generatd missile impact on composite wall systems
… composite wall systems to be used for occupant protection. In order to advance the understanding of the responses of the wall systems to impact, the wall systems will be designated using concepts based on impact djoiamics. However, the majority of impact dynamic concepts are based on …

Dynamic impact induced by tornadoes through simulations based on two-way wind-structure interactions
… codes, in order to provide a better level of occupant protection from tornadoes and to minimize the tornado-induced damage. This requires in-depth understanding of the wind characteristics of tornadoes and their wind effects on civil structures, based on which design tornadic wind loading can …

Development of a Deflection Measurement System for the Hybrid III Six-Year Old Biofidelic Abdomen
… for children ages 5 to 14. Enhancement of child occupant protection depends on the ability to accurately assess the effectiveness of restraint systems. Booster seat design and proper belt fit require evaluation using child anthropomorphic test devices, yet biofidelity of the abdomen and pelvis of …

Head impact characterization of generic A-pillar of an automobile
The need to provide enhanced occupant protection for all impact conditions experienced in automobile crashes poses a great challenge. Several safety features such as seatbelts and airbags have been developed to reduce occupant injuries in the event of a crash. However, new studies have indicated …

Validity of Self-Reported Data on Seat Belt Use: The Behavioral Risk Factor Surveillance System.
… reduce the risk of death and serious injury of occupants in motor vehicle crashes.</p> <p>The Centers for Disease Control and Prevention (CDC) and NHTSA monitor the use of seat belts by surveying the population. The CDC annually conducts a telephone survey called the Behavioral Risk Factor …

A Finite Element Model of the Pregnant Female Occupant: Analysis of Injury Mechanisms and Restraint Systems
… of motor vehicle accidents involving pregnant occupants, as well as the effect of seatbelts on fetal survival, previous research has not produced a tool for engineers to use to improve the safety of a pregnant occupant in a motor vehicle. The goal of this project was to develop a model that can …

Investigating the Thoracic Biomechanical Responses of Rear Seated 50th Percentile Male Anthropomorphic Test Devices and Post Mortem Human Surrogates During Frontal Motor Vehicle Collisions
… be evaluated. Previous research has shown that occupant protection in the rear seat is disproportionately lower than that of the front seat in modern vehicles due to the focus on front seat occupants in both regulatory and market-driven crash tests. This has resulted in many of the occupant …

Modelling the crashworthiness of specialist wheelchair devices
… a vehicle during transportation. Reasons for an occupant to remain in the wheelchair during transport may be the inability to safely transfer to a vehicle seat, the occupant's requirement of a specialist postural management wheelchair seating system or reliance on life support equipment attached …

Effects of Intervention on Booster Seat Purchase: A Field Study
… For this reason, the use and correct use of occupant protection for 4-9 year old children in particular needs to be addressed. For proper restraint, children who have outgrown child safety seats require booster seats used with vehicle lap/shoulder belts. This present study attempted to …

Structural Optimization of Thin Walled Tubular Structure for Crashworthiness
… bumper, side frame rails, steering column, and occupant protection devices like the knee bolster should all exhibit controlled deformation and collapse behavior. This investigation introduces a methodology to design dynamically crushed thin-walled tubular structures for crashworthiness …

Nonlinear Dynamics in Metamaterials under Elastic and Plastic Excitation and Spectral Submanifold Parameterization
… of vibration and damage mitigation, drop protection, and occupant protection. These scenarios demonstrate the ability of elastic metamaterials to mitigate damage by rejecting select elastic-plastic frequency content, moderate impulsive loading through engineered dispersion, and localize …

Protection of Rear Seat Occupants Using Finite Element Analysis
… occur in the front seats because the majority of occupants sit in the front seats. Traditionally, the rear seats were safer than the front seats because a front seated occupant would be closer to rigid structures such as the steering wheel, and they would be closer to the location of the impact. …
