A theoretical and experimental study was conducted on stress waves and ballistic performance of weakly coupled stacks of AlN tiles bonded by thin polyurethane films. The cylindrical projectile was made of tungsten alloy with L/D = 6 weighing 61g at a velocity close to 1170 m/s striking the stack centrally. Total thickness of the stack ranged between 3" and 1.5", and with individual tile thicknesses ...
