Numerical Simulation of Fluid-Structure Interaction Relations between Skull and Brain Based on ALE and Overlapping Mesh Methods

Abstract:

To simulate skull-CSF-brain interaction relations, a simple finite element head model is established, based on ALE (Arbitrary Lagrangian-Eulerian) and overlapping mesh methods. The responses of head under impact was simulated with this model. The numerical results are coincidence well with the experimental results conducted by Nahum et al. What’s more, it is found that the skull-brain relative displacement and brain injury may be predicted better with the ALE method.
