Abstract
This study investigated mechanical properties of brain–skull interface, important for surgery simulation and injury biomechanics. Direct examination of brain–skull interface is difficult due to its delicate nature and complex geometry that follows the skull and brain surface. Hence, we conducted uniaxial compression tests on samples containing skull, meninges and brain. We combined sophisticated measurement data with non-linear finite element analysis to obtain the properties of brain–skull interface. Skull was considered a rigid object as forces obtained were very small to induce any measurable deformation on it. Surface contact model between brain and skull was used to simulate the brain–skull interface. Good correlation between sample deformation in experiment and simulation was used to confirm the brain–skull interface property.
