Simulations of the haemodynamics in the elatic model of vascular graft
Konfršt, Jiří
The paper presents simulation of blood flow in elastic model of crimpted vascular graft (produced by VÚP-Brno CZ; type Ra; internal diameter 9 mm). The LDA method has been used for the investigations of pulsatile flow inside the model. Measurements are realised using three Re numbers with Newtonian and non-Newtonian fluid, wich simulate rheological characteristics of blood.

Contact pressure between head and helmet loaded by external forces
Micka, Michal ; Jírová, Jitka
The simple test of the bike helmet loaded by statical forces on the top of the head is simulated using program ANSYS. The standardized model for laboratory tests of helmets is used as the model of the head. The goal of the project is to obtain details about contact forces or stresses between the cranium and the helmets, which will be used for future development of safety helmets or by modelling of a hurt of the head at accident.
