Abstract

An improved model of the human thorax, utilizing the 3-dimensional finite element computer code DYNA3D (1), is under development. Like the precursor (2) 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 and strain in the interior thoracic volume under these conditions is examined. Plans for further model enhancement and applications are discussed.
