摘要
在交通事故中,颅脑损伤因其高发率和高致命率成为最严重的损伤。颅脑有限元模型成为开展头部损伤研究的重要工具。模型中脑组织所应用的本构模型及材料属性是决定颅脑损伤预测结果的关键因素。本文旨在针对应用于模拟脑组织的本构模型和材料属性进行综述,从而深入理解脑组织生物力学特性,为颅脑损伤的有限元研究提供参考。
Brain injury has become the most severe injury in traffic accident due to its high incidence and high fa- tality rate. The brain injury model plays a critical role in researches on brain injury. The constitutive model and the material properties used in the model are key factors in determining the accuracy of injury prediction. The present paper aims to review the application of constitutive models and material properties in brain simulation so as to bet- ter understand biomechanical properties of brain and provide references for finite element researches on brain in- jury.
