Popis: The new ballistic tests on different glasses and/or at different projectile velocities have led to interesting considerations. The results of the impulsive tests have been the expected ones, while the ballistic test results, not always the expected ones, have given useful information. When the sandwich 22 mm thick is hit by the projectile at 360 km/h velocity, the whole sandwich (different from the 28 mm one), is involved in the impact phenomenon and thus, the whole sandwich adsorbs the impact energy; this behavior must be considered by the designers and by the purchasers. When the new multilayer 28 mm sandwich is hit by the projectile at 460 km/h velocity, the different macroscopic and local behaviors (with regard to the previous 28 mm one), can help to understand the impact phenomena: as the velocity increases, the involved area decreases, the crater gets deeper, the stiffness of the involved area gets higher.
