description: Main objective of this work was to develop finite element (FE) model of human head to predict severity of injury due to various impact scenarios such as: 1) direct hit to the head with object; 2) pedestrian collision with vehicle; 3) head to head impact etc. First part was focused on comparison and validation of analytical solution with FE modeling. In the beginning three problems, effects of which can be observed in simplified model of the head, are discussed: 1) bending of thin spherical shell; 2) Hertz contact problem; 3) energy loss during impact of two objects. All problems were solved in LS-Dyna and results were compared with analytical solutions. Deflection difference is 7 %, contact force varies by 3 % and energy loss is within corridors of analytical solution (authors report different results, maximum difference between results is 20 %). Then analytical solution for simplified human head modeled as fluid-filled spherical shell was compared with FE results. Contact force differs by 5 %, time of impact was almost the same (difference is less than 1 %), acceleration in center of gravity (COG) differs by 1 %. Overall, analytical solution shows good agreement with FE result for different impact velocities. Second part describes development of FE head model based on MRI scans from open access database. Mechanical properties and material models of bones and brain were validated with experimental data. Also behavior of whole head model (such as acceleration in COG, contact force) was compared with different impact scenarios (frontal, vertical and side). HIC was chosen as main injury criteria. Also pressure, stress and strain in different parts of brain were considered as possible criteria because in some cases (rotational motion) HIC unable to predict injury.
