This selection deals mathematically with the cumulative effect of hape charges an the jets forme from he metal liners of suc charges. The cumulative effect obt ine off rs an ppreciable incr ase in t e local penetr tion action of the explosion The effect is brought about by using charges which have a cavity on one of the ends. If such a charge is initiated from the opposite end, the explosive effect in the direction of the cavity axis is found to be much greater than if ordinary charges re used I T AS E TABLIS ED EXPERI ENTALLY THAT IF THE URFACE OF A CUMULA IVE CAVITY I COVERED WITH A RELATIVELY THIN METAL FACING liner the armorpiercing action of the cumulative charge is increased many times.
