"Paper presents a detailed \uFB01nite element model of human head used for head injury criteria assessment. Today most used HICs are based on the history of linear acceleration only. However, the rotational acceleration plays also important role, due to the rupture of bridging veins involved in the relative motion between the skull and the brain. Presented model allows for new approach to de\uFB01ne the HIC based on either strain energy or on combination of linear and rotational acceleration history. The model is based on a series of CT and MRI scans of a cadaver head of high resolution and is composed of three different regions: 1. skull, 2. brain and 3. subarachnoidal space. Discussion on material properties of these four distinct regions is given in the paper." . "Engineering mechanics 2006" . . . "[8058F54BF2AB]" . . "Praha" . "2"^^ . .
