Abstract: | The propagation of waves produced by pendulum impact both radially and obliquely on two different models simulating a head-helmet system was studied experimentally by means of strain gages attached to the surfaces of the components representing the skull and the helmet and by tourmaline crystals embedded in a gel representing the brain. The first model consisted of a set of nested aluminium and styrofoam full or partial spherical shells, while the second comprised an actual cadaver skull held in an army helmet by means of a polyurethane foam. The results were compared with theoretical and experimental information previously developed. |
