Research Abstract |
The purposes of this study were to construct a head physical model having a real human shape by using CAD/CAM technologies, and measure shear strain distribution and propagation in the brain model under rotational impact. A 3D head physical model was constructed from CT and MR images of a subject. The model consists of a skull, falx, cerebrospinal fluid (CSF) and brain. Full-field deformation behavior on the coronal plane of the brain was measured by using digital image correlation (DIC). As the results, shear strain at corpus callosum, surrounded ventricles and longitudinal fissure of cerebrum, showed biggest value. The results correspond to the characteristics of occurrence of diffused axonal injury. Therefore, complex shape of brain and the relative motion between the skull and brain affect on the mechanism of traumatic brain injury.
