BREAKING STRENGTH OF THE HUMAN SKULL VS IMPACT SURFACE CURVATURE

An investigation has been conducted into the effects of surface shape, hardness and impact location on the heads of human cadavers. This is the second year of a study involving eighty cadavers and most of the important results and conclusions are listed and discussed in this report. Impact surfaces included flat rigid and resilient, rigid cylindrical 1/8 in. radius up to 1 in. radius, resilient cylindrical 1 in. radius and rigid hemispherical shapes ranging from 3 in. to 8 in. radius. Impact locations include front, side and rear. The various impact conditions are related to type of skull fracture produced and several head injury parameters such as, velocity, peak force, acceleration, contact pressure and magnitude, and head injury criterion (HIC).
