The Influence of Gyri and Sulci on the Skull-Brain Motion Based on Two Two-Dimensional Finite Element Models
The relative displacement between the skull and brain can be caused by road accidents and leads to permanent health issues or even death. The objective of this study is to investigate the influence of gyri and sulci on skull-brain motion with two two-dimensional finite element head models with detailed structures. The material properties were adopted from the relative literature and assigned to the different model parts. Firstly, frontal impacts were simulated by impacting the head models with the same box-shaped object respectively to enable a comparison between simulation results and experiment data. Next, the same load condition of Nahum’s experiment reported in the literature was used as input to the finite element models. The results indicate that the influence of gyri and sulci on skull-brain motion is not significant.
