Explosively-Separated Tongue and Groove Joint.

A pair of structural members are coupled by a tongue and groove joint having a groove half and a tongue half. To secure the joint, bolts extend transversely through aligned bolt holes and, on each side of the tongue half holes, are so-called collapsing slots. A linear explosive is placed in the base of the groove near the inner end of the tongue. The metal thickness of the tongue lying between the explosive and its holes and slots forms a web which, upon detonation, collapses into the slots. The collapse stretches the web portion adjacent the bolt holes sufficiently to produce a rupture or opening through which the bolts pass to permit separation of the structural members. The separation also is responsive to the explosive force so that the members are accelerated apart in opposite directions. Author
