This article first describes modeling and analysis of relatively rigid head impacts with upper interior structures and compares results with laboratory test measurements. In addition to demonstrating the capacity of a well defined model to accurately replicate dynamic response and to predict levels of injury mitigation obtainable from structural modification, such models are also capable of estimating physical quantities (e.g. detailed stress/strain patterns) known to affect the functional capacity of brain tissue. Measuring these quantities in a test program would be virtually impossible. To provide estimates of such quantities, a first generation anatomic brain model was developed to estimate strains induced in the brain as a result of typical head impacts sustained in automotive collisions. The latter model is viewed as the first step in a complicated process, leading towards the ability to assess soft tissue injuries, and to the development of an expanded head-injury criteria which addresses specific forms of brain injuries known to result from automobile crashes.
