인체 허벅지에 총탄 피탄 시 피탄위치에 따른 동맥손상확률 예측

Abstract

Gunshot injury exert a great influence on survivability of soldiers in battle field. When received gunshot wounds in the arm or leg, excessive bleeding by artery rupture is significant cause of death. Therefore, the purpose of the present study is to predict artery rupture probability when received a gunshot wound in the thigh using finite element method. Gelatin is generally known as similar to human soft tissue. So, we assumed that properties of human flesh is equal to that of 10% gelatin. The properties of gelatin are obtained through indentation test. In this study, ANSYS was used for finite element analysis. The analysis method we used is validated by comparing deformation of gelatin penetration simulation with experiment. We simulated artery maximum elongation according to gunshot position. And we calculate artery rupture probability when receive a gunshot wound in the thigh by using artery yield elongation experiment results of other reference.
