Development and Validation of a Finite Element Dummy Lower Limb Model for Under-body blast Applications
… (UBB) refers to the use of a roadside explosive device to target a vehicle and its occupants. During Operation Iraqi Freedom, improvised explosive devices (IEDs) accounted for an estimated 63% of US fatalities. Furthermore, advancements in protective equipment, combat triage, and treatment have …

Head and Neck Injury Risk Predicted by Finite Element ATDs and Human Body Models in the Aerospace Landing Environment
… is not complete. Currently, the Hybrid III and Test Device for Human Occupant Restraint (THOR) are in use for assessing injury risk to future occupants of spaceflight vehicles, but both were developed for primarily frontal MVC conditions and scenarios much more severe than those expected to be …

Injury Biomechanics of the Human Eye During Blunt and Blast Loading
… upon direct inspection of the globe following testing. No serious eye injuries were observed for any of the tests and all tests resulted in low predicted injury risks consistent with the lack of observed injury. The research presented in this thesis provides a robust low injury level dataset …

Development of a Deflection Measurement System for the Hybrid III Six-Year Old Biofidelic Abdomen
… proper belt fit require evaluation using child anthropomorphic test devices, yet biofidelity of the abdomen and pelvis of the current anthropomorphic test device, the Hybrid III 6-year-old, needs improvement. Further, measurement of abdominal deflection is needed for quantification of the degree …

Development of a Comparison Technique Between Crash Tests and Real-World Crashes
… a repeatable method for finding similar crash tests to compare to real world crashes using the Crash Injury Research and Engineering Network (CIREN) database and common crash test databases. Each of the Toyota-Wake Forest University CIREN cases with horizontal principle direction of force …

Lower Extremity Biomechanical Response of Female and Male Post-Mortem Human Surrogates to High-Rate Vertical Loading During Simulated Under-Body Blast Events
… blast (UBB) event, an improvised explosive device (IED) delivers a high-energy blast beneath a military vehicle, exposing mounted Warfighters to considerable risk of severe lower extremity injuries. Loftis and Gillich (2014) determined that the lower leg and ankle region is the most common …

Exploring the Link Between E-scooter Crash Mechanism and Injury Outcome Using Finite Element Analysis
… element (FE) model of a standing Hybrid III anthropomorphic test device was used as the rider model after being calibrated against certification test data. The angle of approach was found to have the greatest effect on injury risk to the rider, and it was shown to be positively correlated …

Cervical Spine Tolerance And Response In Compressive Loading Modes Including Combined Compression And Lateral Bending
… have observed noticeable lateral bending of the anthropomorphic test device (ATD) neck prior to or in conjunction with head impact with the vehicle roof in rollover crash tests. Since there is scant data available about the effects of lateral bending on overall compressive tolerance of the human …

An investigation of the forces within the tibiae at typical blast loading rates : with different boots
… (AVLs), underbelly Improvised Explosive Devices (IEDs) or side-attack IEDs are some of the major threats to military vehicles and their occupants (Ramasamy et al., 2011). The lower extremities of the occupants are very prone to injury, mostly caused by underbelly detonation of AVLs or …

Biomechanical Responses of Small Female Human Surrogates during Frontal Sled Tests using a Realistic Vehicle Environment
… The THOR 5th-percentile female (THOR-05F) anthropomorphic test device (ATD) was developed to represent a small female occupant better than the Hybrid III 5th percentile female (HIII-05F) ATD. However, the two ATDs have not been compared to post-mortem human surrogate (PMHS) responses using …

Anti-Rotation Load Leg Effects on Crash Injury Metrics Under Child Restraint System Misuse
… other internal organs). Although anti-rotational devices, such 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 …

Simulated Automobile and Rotary-Wing Aircraft Impacts: Dynamic Neck Response after Surgical Treatment for Cervical Spondylosis
… aircraft impact with the ground using both an anthropomorphic test device (ATD) and a human body model. The head and neck response of the ATD FE simulation was successfully validated against the results of a previously conducted experimental sled test. A more biofidelic head and neck response …

Study of Occupant Model Capability to Quantify Injury Risk for eVTOL Vehicles
… (LaRC) previously conducted a full-scale crash test of a Fokker F28 MK1000 aircraft to study occupant injury risks. The goal of the current study was to investigate the injury predictions of the Global Human Body Models Consortium (GHBMC) and Total Human Model for Safety (THUMS) occupant models …
