Abstract
A simplified finite element model of a human torso has been developed in order to investigate and predict the biomechanical response of an actual torso to blunt ballistic impacts. The model consists of a simplified three-dimensional human torso. The torso was impacted with a non-compressible polyvinyl chloride cylinder. The projectile is a cylinder 37 mm in diameter and either 28.5 mm or 100 mm long. The purpose of this study was to validate the biomechanical response model with the results of experiments on post mortem human subjects published in the open literature. The chest dynamic deflection, the dynamic force applied to the chest and the force applied to the chest as a function of chest deflection were compared and validated with the experimental data. Substantial agreement between the numerical model and the experiments was achieved.
