Lecture: Passive safety of vehicles

Lecturer: Prof. Dr. Ing. Axel Schumacher


• Passive safety – A stone in road safety

• Accident statistics

• Mechanical bases to the description of collision processes

- General description of shock processes

- Accelerations with the collision of two vehicles

- Structural load with the collision

- Stability problems

- Plasticity

• Methods of the numerical calculation of crash processes
