对1982~1992年间发表的有关头部碰撞有限元模拟的论文进行了综述。关于本十年所取得进展的主要结论可概括如下。所使用的构造模型主要是线弹性或粘弹性，前者几乎都与小变形理论相结合，而后者则考虑大变形。只有一个模型同时考虑了非线性粘弹性和大变形。由于缺乏一致和完整的实验数据，这类复杂模型的使用继续受到阻碍。已经成功地实施了更现实的边界条件，允许头骨和大脑之间的相对运动。头颈部交界处的边界条件需要进一步研究。对于不同几何形状的模型和在子结构之间界面具有不同边界条件的相似形状的模型，应用比例方法也是如此。越来越多的人使用物理模型来验证有限元建模技术，并作为参数研究的起点。(A)会议的封面摘要见IRRD 860654。
A review is given of papers on finite element modeling of head impact that have been published in 1982-1992. The main conclusions as to the progress made in this decade can be summarized as follows. The constructive models used are predominantly linearly elastic or viscoelastic, the former almost all in combination with small- deformation theory and the latter with large deformations. Only one model included both non-linear viscoelasticity and large deformations. Utilization of this type of sophisticated models continues to be hampered by the lack of consistent and complete experimental data. Successful efforts have been made to implement more realistic boundary conditions allowing relative motion between the skull and the brain. Boundary conditions at the head-neck junction need further investigation. The same holds for the application of scaling methods to both models with different geometries, and similar- shaped models with different boundary conditions at the interfaces between the substructures. Increasing use is made of physical models both for validating finite element modeling techniques and as a starting point for parametric studies.
