Computational Modeling of Thoracic Injury Response due to Impact of a Small Unmanned Aerial System (SUAS)
… a computational model that will predict the injury response after a sUAS impacts the thorax. A rotary and fixed winged sUAS were chosen for analysis. A vast number of numerical simulations were carried out with varying masses, impact velocities, and impact angles. From the simulation results, …

The Biomechanics of Thoracic Skeletal Response
… impact collisions, it has been reported that thoracic injuries are the most common type of serious injury (AIS≥3) to vehicle occupants in both near side and far side crashes which do not involve a rollover. In addition, rib fractures are the most frequent type of thoracic injury observed in …

Investigating the Thoracic Biomechanical Responses of Rear Seated 50th Percentile Male Anthropomorphic Test Devices and Post Mortem Human Surrogates During Frontal Motor Vehicle Collisions
… occupant injuries. However, the biofidelity and injury risk criteria used for these ATDs has only been validated when seated in the front seat. To validate the response and injury risk predictions of existing frontal ATDs in the rear seat it is necessary to generate new biomechanical data in the …

Characterisation and investigation of serious thoracic injuries in passenger vehicle rollover crashes
… efforts, the characteristics and aetiology of thoracic injuries in rollover crashes are still not well understood. It has been hypothesised that these injuries are occurring as a result of occupant flailing within the vehicle during the rollover crash event. Four studies were performed and …

Morphological Analysis of Changes in the Thoracic Skeleton with Age and Gender
Thoracic anthropometry variations with age and gender are expected to affect thoracic injury mechanisms and tolerance. The objective of this research was to quantify the age and gender-specific variations in the thoracic skeletal morphology for both genders and across the entire age spectrum (ages …

Biomechanical Responses of Human Surrogates under Various Frontal Loading Conditions with an Emphasis on Thoracic Response and Injury Tolerance
… ATDs must be evaluated, and the mechanisms of injury must be understood in order to accurately predict injury. Evaluating the biomechanical response, injury mechanisms, and injury threshold of the thorax are particularly important because the thorax is one of the most frequently injured body …

Characteristics of Thoracic Organ Injuries in Frontal Crashes
… of airbags has not significantly reduced serious thoracic injury for belted occupants in frontal crashes. This thesis has investigated the effectiveness of airbags and the characteristics of residual thoracic organ injury incurred by belted occupants in vehicles equipped with airbags. This study …

A Biomechanical Assessment Of Canine Body Armor
… armor blunt impact, 3) the identification of an injury criterion that will best predict canine thoracic injury as a result of behind armor blunt trauma, 4) correlation of the behind armor blunt trauma response to the standard backface testing medium (clay), and 5) the evaluation of commercially …

Feasibility Study of Low Dose Chest CT for Initial Evaluation of Blunt Chest Trauma Patient
… evaluation of the polytrauma patients including thoracic injury. However, the routine use of CT results in rapid increase of the CT radiation dose in blunt chest trauma evaluation. Therefore, according to the ALARA (as low as reasonable achievable) principle, radiation dose adjustment in the …

Tensile Material Properties of Human Costal Cartilage Perichondrium
… the most common injuries resulting 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 …

Anti-Rotation Load Leg Effects on Crash Injury Metrics Under Child Restraint System Misuse
… as load legs, have shown potential in mitigating injury metrics, their efficacy for rear-facing infant CRS misuse conditions and condition combinations remains underexplored. Therefore, this research aimed to evaluate the use of load legs on head and neck injury metrics under two common misuse …

Influence of Advanced Airbags on Injury Risk During Frontal Crashes
… in crashes continue to be at risk of serious thoracic injury. One hypothesis is that this risk may be due to the lack of airbag deployment or the airbag \'bottoming-out\' in some cases, causing drivers to make contact with the steering. The objective of this study is to determine the influence …

Effects of Sex, Strain Rate, and Age on the Tensile and Compressive Material Properties of Human Rib Cortical Bone
… provide data that allows FEMs to better assess thoracic injury risk for all vehicle occupants. Additionally, this study provides the necessary data to more accurately model and assess differences in the material response of the rib cage for nearly all vehicle occupants of driving age.

Material Properties of Human Rib Cortical Bone from Dynamic Tension Coupon Testing
The purpose of this study was to develop material properties of human rib cortical bone using dynamic tension coupon testing. This study presents 117 human rib cortical bone coupon tests from six cadavers, three male and three female, ranging in age from 18 to 67 years old. The rib sections were …

Development of a Finite Element Based Injury Metric for Pulmonary Contusion
… second only to the head in terms of frequency of injury following MVC, and pulmonary contusion (PC) is the most common intra-thoracic soft tissue injury sustained as a result of blunt chest trauma. The goal of this dissertation research is to mitigate this commonly-sustained and potentially life …
