Peeling of aluminium tubes as an efficent method for energy absorption in vehicle front structures

Kurzfassung

Current crash structures in cars are still using the buckling of metallic structures to absorb the kinetic energy in case of an impact. The disadvantage of this technology is that changes within the static structural behavior, like e. g. the stiffness or eigenfrequencies, will cause changes in the crash behavior, even if this is not desired. This correlation between static and dynamic behavior causes many development loops to adjust the crash behavior, e. g. through optimizing trigger geometries which lower the initial crash forces.
