Barrier damage modes evaluated through finite element modeling. Damage Mode Field Example FE Model Rail and Post Deflection Missing Post Separated Rail / Post Rail Flattening 3.5 Validation of the Finite pled vehicle-roadside hardware models, (2) validation against Element Models full-scale crash tests involving damaged barrier, and (3) vali- dation against component tests conducted with a pendulum Proper validation of the finite element models is crucial to impact rig. In each case, the finite element models were able the accuracy of the simulations. The validation plan for the to faithfully reproduce the corresponding impact experiment. finite element simulations was as follows: (1) validation of cou- Details of the validation studies are provided in the appendices.
