SIMULATION OF HEAD INJURY DUE TO COMBINED ROTATION AND TRANSLATION OF THE BRAIN

This paper describes a mathematical model for head injury prediction based on the hypothesis that injury results from a combination of displacement and rotation of the brain inside the skull. The model is a 12-degrees-of-freedom mechanical system consisting of masses, dashpots, and springs. The classical Lagrange's method is used in formulating the equations of motion. Numerical integration is used to obtain their solution. The frequency and time responses of the model, for a variety of loading conditions, are studied. Results show a good agreement between experimentally observed and mathematically generated responses.
