Aspect of the 3/8" thickness plate, 50 mm x 50 mm, of the titanium alloy, in a section transverse to the impact position that is to the top of the figure. The projectile did not perforate the plate but caused a localized plastic deformation and cracks that appear in the opposite site of the plate at the projectile impact position.
