• Description:
  Traumatic brain injuries (TBI) are among the most common severely disabling injuries in the U.S. Approximately 1.7 million cases occurred in civilians annually during 2002-20061. The Finite Element (FE) method has been widely used to investigate the injury mechanism of TBI, because it is technically difficult to quantify the responses of the brain tissues to impact in experiments. One of the technical challenges to build a FE model of a human head is the modeling of the cerebrospinal fluid (CSF) of the brain. The CSF is a body fluid that occupies the subarachnoid space and the ventricular system around the brain and spinal cord. In the current study, we proposed an improved FE model of human head-brain complex, in which we applied membrane elements to construct the CSF layer. [Description provided by NIOSH]
