AN IMPROVED FINITE ELEMENT MODEL OF THE HUMAN THORAX

This paper describes the development of an improved model of the human thorax, utilizing DYNA3D, a three-dimensional finite element computer code. Like the precursor to this model, the thorax is represented by elastic bone, ligament and cartilage, viscoelastic muscle and interior elements, and a rigid body impactor. The current model is an accurate representation of a 50th percentile male with regard to skeletal anatomical structure, overall dimensions and mass. Mesh development and preparation for input to DYNA3D are discussed. The dynamic response of the model under impact conditions is compared to available cadaver data. Strain in the interior thoracic volume under these conditions is examined. Plans for further model enhancement and applications are discussed.
