Physical and computational models are often used as tools to study traumatic brain injury (TBI). The usefulness of such models relies heavily on the accurate representation of the internal structure, an accurate description of the behavior of the materials involved, and the use of an appropriate measure of injury. We present experimental techniques for the measurements of the macroscopic and microscopic behavior of the white matter in the brain. We then develop an injury model for diffuse axonal injury based on an axonal strain injury criterion. This neural damage occurs primarily in the deep white matter regions of the brain.
