Experimental and analytical investigations were conducted to obtain basic knowledge on the influence of the charge shape on the local failure of concrete slabs subjected to contact detonation. The results showed that the damage depth of the slabs varied depending on the charge shape, and the effective amounts of explosives based on Kennedy’s knowledge might be a useful parameter for evaluating the damage depth. However, it was considered necessary to develop another parameter to evaluate the flying velocity of the concrete fragments due to the spall failure.
