The dissertation discusses human body modelling for traffic accident analysis. The individualized modelling procedure considers anthropometric variations and collision initial conditions, thus efficiently neutralizing the unreliability of widely used validation corridors. Moreover, the modelling procedure enables better prediction of occupant motion during vehicle collision and thus more precise estimation of possible injuries in real-life traffic accidents.

The book chapter thoroughly discusses methods for obtaining some biomechanical data needed in traffic accident analysis. Principles of human body modelling are introduced, together with their main features and software implementations. Models based on multibody system dynamics appear to be robust in numerically effective. FEM models enable localized stress-strain analysis in human body tissues. Among the methods of body segment properties estimation, the method of medical imaging and geometric reconstruction is presented in detail.

In the presented study four fixation techniques for a collagen fleece used as autologus chondrocyte scaffold were compared in the cadaveric knee joints. After each simulated surgical procedure the knee joints were exposed to the continuous passive motion with and without loading, thus simulating also early postoperative rehabilitation. To our knowledge, this is the first study that directly compared different operative fixation techniques together with the simulation of the postoperative passive motion within the same model.

Magnetic resonance imaging MRI and transesophageal ultrasound (US) were the methods chosen for detection and characterization of central pulmonary emboli. The results of both imaging methods were compared with immunohistochemical analysis. MRI showed corresponding results to the red cell-rich regions, while US provided other clot details. MRI and US imaging techniques were proven to be effective in characterization of pulmonary emboli, thus enabling proper treatment. The study established new information about medical imaging methods and diagnostics of pathological tissue changes and injuries.

The paper presents numerical analysis of the actual carrying capacity of the rolling contact in single-row ball bearings and the verification of a numerical material model in a computerised test stand. For the purpose of the numerical analysis of the actual carrying capacity of rolling contacts in large rolling bearings with surface-hardened raceways, an elasto-plastic constitutive model was developed which links the mechanics of material damage with the isotropic and kinematic hardening/softening. It allows us to monitor the plastic strain increase, stress changes and material damage growth.
