ABSTRACT
In order to study the biomechanics of cerebral trauma, including brain injury mechanisms and tolerance to impact, three-dimensional models of human and porcine brains were constructed. Biomechanics is concerned with how the anatomy of the skull and brain contributes to Traumatic brain injury. It describes the interaction of physical forces with the structure of the torso, neck, head, and brain as tethered to the spinal cord. Human body dynamics analysis refers to the mechanical understanding of what happens to the person in the course of an accident. The direction of the body and impacting object determine the planes of brain movement and rotation. Impact creates brain movement and impact against other structures, pressure waves, skull fractures, and brain indentation. Shearing refers to the differential speed of movement of adjacent tissues that result in scraping injuries of the brain against the inside of the cranium and the separation of brain planes.
