Abstract. Two grades of armor ceramic have been subjected to high
velocity impact by small steel spheres. The depth of penetration,
crack formation and the extent of comminution have been characterized.
In particular the formation of the Hertzian-type conical fractures has
been analyzed and compared with other experimental results. A ranking
method has been employed which calculates the relative mass advantage
of using a ceramic over an aluminium material. It is
found that, for this experimental program, using a harder alumina
of lower fracture toughness provides better protection than that given
by a softer, tougher grade. However, the advantage of using
this ceramic diminishes as the impact velocity is increased. This
paper will be interest to the armorer who is concerned
with high explosive fragmenting ammunition.
