Consider a pedestrian, a car and an accident. In road traffic accidents, pedestrians often sustain the worst injuries if their head hits the windscreen. A highly complex simulation process has now enabled TECOSIM to map the consequences of a head impact on laminated glass in a realistic, efficient way using a computer for the first time. This new process is the result of a state-funded research project. Glass simulation can now be used to improve pedestrian and road safety right from very early stages of vehicle development.
