The previously developed thoracic finite element model [8, 9] was used to investigate the human thoracic dynamic responses associated with the frontal, lateral and oblique loading and to predict injuries of the thorax associated with the frontal loading. The thoracic model was developed [8, 9] to improve the human articulated rigid body model ROBBY (the model of an average adult male) [13, 14], which was previously developed at the University of West Bohemia in cooperation with ESI Group (Engineering Simulation for Industry). There are implemented deformable models of the thorax and abdomen in the ROBBY model. The geometries of individual thoracic organs were based on the cadaver tomography data and color cross-section photographs obtained from Visible Human Project (VHP) [33]. The thoracic model material properties were obtained either by virtue of cooperation with ESI Group or from public sources (articles, Internet, books). Thoracic model includes the models of the sternum, ribs, costal cartilages, vertebrae, lungs, heart, trachea, main vessels (aorta, vena cava superior), intercostal muscles, diaphragm, flesh and skin. The presented study deals with the dynamic response and validation of the whole thoracic model and with the prediction of thoracic injuries by virtue of this model. The results of simulations are compared with the experimental results. and Obsahuje seznam literatury
