Multi Directional THOR Testing Comparison to an Updated FE THOR Model Authors: Derek A. Jones, Kyle P. McNamara, James P. Gaewsky, Ashley A. Weaver, and Joel D. Stitzel—Wake Forest School of Medicine, Virginia Tech – Wake Forest University Center for Injury Biomechanics; Jacob B. Putnam and Jeffrey T. Somers—KBRwyle Abstract The use of anthropomorphic test devices (ATDs) for calculating injury risk of occupants in spaceflight scenarios is crucial for ensuring the safety of crewmembers. Finite element (FE) modeling of ATDs has…

Leveraging Human Body Models of Varying Complexity for Computational Efficiency Authors: Berkan Guleyupoglu, Bharath Koya and F. Scott Gayzik—Wake Forest University School of Medicine, Virginia Tech – Wake Forest Center for Injury Biomechanics Abstract The objective of this study was to reduce the computational cost of human body model (HBM) simulations by developing a method to switch between models of varying detail during an event. One application is simulations involving active safety systems where the total simulation time can greatly…

Pedestrian Flex-PLI Legform Test Performance for Seven Early 2000s’ Small Cars Authors: Becky Mueller and Joseph Nolan—Insurance Institute for Highway Safety (IIHS) Abstract IIHS is examining the potential real-world benefit of vehicle-based pedestrian tests, such as those proposed by NHTSA for future safety ratings. Laboratory pedestrian headform tests of seven popular small cars from the early 2000s predicted a range of pedestrian head protection for these vehicles. Comparing test results to fatal and incapacitating injury rates for these vehicles from US…

Effect of Postmortem Time and Preservation Fluid on the Tensile Material Properties of Bovine Liver Parenchyma Authors: Kristin M. Dunford and Andrew R. Kemper—Virginia Tech-Wake Forest University, Center for Injury Biomechanics; Tanya LeRoith—Virginia-Maryland College of Veterinary Medicine Abstract The purpose of this study was to quantify the effects of postmortem degradation on the tensile material properties of bovine liver parenchyma when stored in DMEM or saline. Fourteen fresh bovine livers were obtained from a local slaughter house and stored in either DMEM or saline as large…

Development of Improved Brain Injury Predictors for Diverse Impacts Authors: Lee F. Gabler, Jeff R. Crandall, and Matthew B. Panzer—University of Virginia, Center for Applied Biomechanics; Norbert Praxl—Partnership for Dummy Technology and Biomechanics; Philipp Wernicke—BMW Group Abstract Tissue-level deformation is the mechanism for brain injury, and rotational head motion is the mechanism for brain deformation. While numerous rotational metrics have been proposed, many do not represent the mechanics principles that govern brain deformation rendering them ineffective for application over…

Belted Female Occupants in Frontal Car Crashes are More Likely to Sustain Moderate Concussions than Male Occupants Authors: Jacobo Antona-Makoshi—Japan Automobile Research Institute; Johan Davidsson—Chalmers University of Technology; Mats Lindkvist—Umeå University Abstract NASS-CDS data from years 2005-2015 was analyzed to estimate the frequency and risk of moderate and serious concussion injuries sustained by belted occupants in car crashes in the US. The concussion data was compared to all other brain injuries of higher severity and analyzed considering crash severity, crash year, car model year, and the victim’s…

Occupant Torso Kinematics in Low Acceleration Time-Extended Evasive Swerving Events Authors: Christine Holt, Sriram Balasubramanian—School of Biomedical Engineering, Science, and Health Systems, Drexel University and Center for Injury Research and Prevention, Children’s Hospital of Philadelphia; Thomas Seacrist, Valentina Graci, and Kristy B. Arbogast—Center for Injury Research and Prevention, Children’s Hospital of Philadelphia; Jason Kerrigan and Richard Kent—Center for Applied Biomechanics, University of Virginia Abstract Low-acceleration time-extended (LATE) emergency maneuver events often precede a crash. The inertial forces during such events…
