Abstract: [eng] [cze]
Article deals with explicit finite element modelling of contact conditions of human head impacting a flat rigid surface. For this purpose, detailed 3-D model of human skull and brain was developed based on a series of computer tomography scans of resolution 512x512 pixels taken at 1 mm distances. The FE model of human skull was filled with simplified model of human brain. The brain is modelled as a homogeneous viscoelastic material. A case study of low-velocity impact to different regions of the human head (e.g. frontal impact and impact in the occipital region) is also modelled. Článek se zabývá explicitní numerickou analýzou nárazu lidksé lebky na tuhou překážku. Tvorba detailního 3-D modelu lebky včetně mozku na základě CT a MRI snímků lidksé hlavy je zde rovněž popsána. Náraz do frontální a okcipitální části hlavy je modelován pomocí MKP.
