Interaction of a moving car with the human body is greatly biomechanically stressed topic that is studied in detail on a number of important sites around the world, both through real-world crash tests and modelling using computational methods. It is a complex issue of mechanically complex system of viscoelastic elements interconnected via links with more degrees of freedom with variable mechanical properties and also managed by the neural system both consciously (in the longer lasting effects) and unconsciously.
Head injury is the most frequent cause of life threat. It is caused by strong impact of the head to some sort of obstacle.
We have used mathematical and physical models for the computational tasks of inverse dynamics that allow us to solve interactional biomechanical conditions in both real and extrapolated extremely-loading situations. Based on changes of input mechanical loading, i.e. changes of static, dynamic, impulse and inertial loading, we have been able to determine appropriate biomechanical reaction and specify the value of the HIC (Head Injury Criterion) which can be approximately correlated to the AIS (Abbreviated Injury Scaled).
