• Abstract:
  Various modeling techniques are playing an increasingly important role as a cost effective means of supplementing crashworthiness data for gaining a better understanding of the injury mechanisms associated with automotive crashes. The interaction of a geometrically accurate (50th percentile male) finite element model of the human thorax, and finite element models of a seat belt restraint system and an airbag are examined. Optimi7.ation of the thorax model under frontal impact conditions as well as the development of an improved shoulder structure are discussed. Using LSDYNA3D, the three-dimensional finite element structural analysis code, stress fields within the thorax model are examined and the results, using each restraint system in a comparable impact environment, are presented.
