Response Analysis of Thoracic Rib-Cage Against Blunt Loading Using Human Elderly FE Model
Published May 23, 2012 by Society of Automotive Engineers of Japan in Japan
The present study analyzed the local response of the thoracic rib-cage against blunt loading using a human elderly FE model. The model was established based on the thoracic CT imaging, representing the average anthropometry of an AM 50th percentile elderly human subject. To develop a local stiffness map of the thorax, a series of simulated frontal impact tests was conducted; longitudinal impact tests with an increment of 25 mm and angular impact tests with an increment of 5 degrees were done. The variation of the local stiffness and the contribution of each thoracic component to the global thoracic deflection were identified.
