3-D finite element analysis on brain injury mechanism

The purpose of this study is to discuss the mechanism of brain injury analytically by a cavitation phenomenon. Cavitation damage is assumed to be one of the causes brain injury. Performing the computer simulation of brain injury, it is not easy to incorporate the term of a cavitation occurrence in a governing equation. Therefore, we predict the cavitation occurrence from the results of stress, pressure, and displacement of the analytical model by FEM.
