Few finite element models of shaken baby syndrome exist, and those either ignore the fluid surrounding the brain or model it as a soft solid. The importance of modelling the fluid properly is demonstrated, and the reliability of MSC.Dytran’s fluid-solid interaction modelling is confirmed. The first three-dimensional finite element model of shaken baby syndrome which accurately includes the cerebrospinal fluid is created and used to estimate tolerance criteria for causing subdural haematoma by shaking.
