[3] [7] [8] These tests consist in normal-to-the barrier impacts in the center of a three-panel barrier by a projectile with translational velocity of at least 25 m/s and no rotational velocity. The response of a barrier may also be evaluated based on specific numerical models, developed based on a finite element method or a discrete element ...
