Numerische Nachbildung der Crashfront von faserverstärkten Strukturen mit Hilfe von Mehrschalenmodellen
The numerical simulation of the crash front in composite structures is up to now difficult. The reason is based on the complex failure phaenomena in the crushing area (fibre fracture, matrix failure, delamination, etc.). To improve ...
