Investigating the Thoracic Biomechanical Responses of Rear Seated 50th Percentile Male Anthropomorphic Test Devices and Post Mortem Human Surrogates During Frontal Motor Vehicle Collisions
Frontal motor vehicle collisions (MVCs) account for the majority of injuries and fatalities in MVCs according to the Fatality Analysis Reporting Systems (FARS). One of the most commonly injured regions of the body during MVCs is the thorax. While there are fewer adult passengers riding in the rear …

Characterizing the Biomechanical Response of Liver
Motor vehicle collisions can result in life threatening liver injuries. Dummies are utilized to study injury in motor vehicle collisions; however, no crash test dummies are currently equipped to represent individual solid organs. This has increased the use of finite element models to help reduce …

The Effects of Child Restraint System Use and Motor Vehicle Collision Severity on Injury Patterns and Severity in Children 8 Years Old and Younger.
Motor vehicle collisions (MVCs) are a leading cause of injury and death for children under the age of 14 years in North America. Children, eight years old or younger, are required to use a child restraint system (CRS) when travelling in a vehicle in Canada. In the present study, the hypothesis that …

The development of evidence-based guidelines to inform the extrication of casualties trapped in motor vehicles following a collision
Background Motor vehicle collisions (MVCs) are a common cause of injury and death throughout the world. Following an MVC some patients will remain in their vehicles due to injury, the potential for injury or physical obstruction. Extrication is the process of removing injured or potentially injured …

Quantifying the Kinematics of Injury Biomechanics: Several Applications Incorporating Human Volunteers and Surrogates
Nearly 27,000 vehicle occupants are killed annually in the United States, with passenger car and light truck occupants amassing 25,000 of these. Over 50% of passenger car and light truck occupant fatalities are due to frontal crashes. Although advancements in safety technology have reduced the …

Effect of Postmortem Time and Preservation Fluid on the Tensile Material Properties of Bovine Liver Parenchyma
… the most frequently injured abdominal organs in motor vehicle collisions. Although previous studies have quantified the tensile failure properties of human liver parenchyma at 48hrs postmortem, it is currently unknown how the material properties change between time of death and 48hrs postmortem. …

Development of a Deflection Measurement System for the Hybrid III Six-Year Old Biofidelic Abdomen
Despite advancements in automotive safety, motor vehicle collisions remain the leading cause of unintentional death 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 …

Preliminary Investigation of the Mechanical Properties of Costal Cartilage and Costochondral Junction in Three-Point Bending
Motor vehicle collisions (MVCs) are a leading cause of morbidity and mortality. The chest accounts for the second most cause of driver fatalities in frontal collisions. The skeletal thorax is composed of the ribs, costal cartilage, thoracic vertebrae, and sternum. Costal cartilage (CC) is a …

Tensile Material Properties of Human Costal Cartilage Perichondrium
… from blunt thoracic loading scenarios, including motor vehicle collisions. The costal cartilage is a cylindrical hyaline cartilage composed of two layers: a core interstitial matrix enveloped by the perichondrium. The perichondrium itself has an inner chondrogenic layer and an outer fibrous layer. …
