Abstract

In this paper, a three-dimensional finite element model of the human thorax was constructed using Mimics software and Icem CFD software. This model was loaded with a 100-kPa blast wave and constructed to analyze the dynamic response of the chest wall. The simulation results have shown that a blast wave can cause stress concentration on the ribs and ribs inward movement. The third, fourth, and fifth ribs have the maximum inward moving velocity of 1.6 m / s without any injury for the human body. The three-dimensional finite element model can realistically reflect the characteristic mechanical response of the chest wall to blast wave loadings and can be used for further studies on blast injury mechanism, i.e., injury prediction.
