中文摘要：

有限元方法（finite element method,FEM）是一种与现代计算机技术相联系的计算应力分析方法,已逐渐被应用于生物力学领域仿真人体结构力学功能研究,尤其是在颅脑损伤研究中最为广泛和深入。本文综述了现有头部有限元模型的特点、材料属性的赋值以及颅脑损伤有限元模型在钝力击打、高坠、交通事故等鉴定中的应用情况,探讨FEM建模在法医学颅脑损伤预测中的优劣势及其应用价值。

英文摘要：

FEM combined with modern computer technology is a mathematical method for stress analysis.It has gradually become a significant experimental tool to explore the functions of biomechanically simulated human body structure and mechanism of craniocerebral injuries.This paper reviewed the features and biomechanical materials of the FEM human head models,materials assignment and their applications in blunt injury,fall,traffic accident.It also explore their merits and values in forensic head injury cases.
