  2. A New Method to Model Aluminium Honeycomb Based Crash Barriers in Lateral and Frontal Crash Load Cases

    Using Finite Element Method (FEM) it is possible to show and predict the behaviour of the vehicle’s structure during a crash test. To ensure good simulation results compared to the reality it is not only necessary to correctly build ...
