Nové kritérium pro stanovení poškození hlavy
 Jiroušek, Ondřej ; Jírová, Jitka ; Brichtová, E.
Detailed Finite Element Model of human head used for head injury assessment is presented in the article. Development of the model based on a series of postoperative CT images of high resolution is shortly described. The model is used in a model situation of a sport accident involving a 12-year old boy on whom a handball cage fell during a sport activity causing a serious injury of the boy’s head. An approach to quantify the injuries caused is described in the paper.

Explicitní MKP analýza nárazu lidské lebky na tuhou podložku
 Jiroušek, Ondřej
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.
