Abstract : A procedure widely used to simulate blow-off impulse loading of shell structures (e.g., reentry vehicles or interveptor missiles) is to apply layers or strips of sheet explosive to the outside surface of the structure, usually separated from this surface by a thin attenuator layer of soft material to prevent spallation from the inner surface. Since this sheet explosive cannot be detonated simultaneously, but is initiated as a plane or curved detonation front sweeping over the structure, some concern has been felt as to whether this procedure will produce the same structural response as the simultaneously applied X-ray loading which it is intended to simulate. A study was conducted in which the responses of fixed-ended cylinders to a frontal cosine distribution of impulse intensity were calculated for three cases: a load pulse initiated simultaneously on the entire frontal half of a cylinder, a plane detonation front sweeping longitudinally and a plane detonation front sweeping circumferentially.
