The aging population is a growing concern as the increased fragility and frailty of elderly results in an elevated incidence injury well risk mortality morbidity. To assess risk, age-specific computational models can be developed to directly calculate biomechanical metrics for injury. first objective was develop older occupant Global Human Body Models Consortium (GHBMC) average male model (M50) representative 65 year old (YO) perform regional validation tests investigate predicted fractures severity with age. Development GHBMC M50 YO involved implementing geometric, cortical thickness, material property changes Regional included chest impact, lateral shoulder thoracoabdominal abdominal bar pelvic sled test. second age-related risks by performing frontal US NCAP simulation test v4.2 models. Simulation were compared evaluate effect age on response head injury, neck thoracic lower extremity Overall, higher probabilities AIS 3+ thorax.
