An explosive device (30, 80, 90, 100, 110, 310, 360) capable of producing an external shock wave front (29, 176) comprises assembled plural charge segments (32, 82, 92, 102, 111, 112, 150, 160, 190, 200, 210, 216, 220, 230, 250, 260, 270, 280, 290, 300, 312, 340, 352) having respective contacting abutment surfaces (34, 86, 98, 108, 115-118, 152, 162, 192, 202, 212, 217, 222, 232, 252, 262, 272, 282, 292, 302, 314, 342, 354) formed on the exterior therof. A cavity (42, 153, 154, 163, 164, 194, 204, 213-15, 218, 219, 228, 238, 274 284, 286, 288, 294, 296, 298, 304, 316, 318, 320) is recessed in one or both of contacting abutment surfaces (34, 86, 98, 108, 115-118, 152, 162, 192, 202, 212, 217, 222, 232, 252, 262, 272, 282, 292, 302, 314, 342, 354). Some cavities (228, 238, 254, 274) are lined or filled with contrastingly high energy explosive material (226, 236, 254, 266, 275). The output end of a transmission line (15, 21, 25) for a detonation impulse (I) generated by a control device (16, 22, 26, 27) is received in such a cavity (42, 153, 163, 194, 204, 215, 218, 219, 228, 238, 274, 284, 286, 288, 294, 296, 298, 304, 316, 318, 320) as is open to the exterior of the assembly. A cavity (153, 154, 163, 164, 194, 204, 213-15, 219, 284, 286, 294, 296, 298, 316, 318) configured to dispose explosive material (165) in the path of a plasma zone (178) propagating through voids in the assembly detonates such explosive material (165) in advance of the normal arrival there of the detonation wave front (28, 174) that trails the plasma zone (178) through the assembly. |
