Abstract:

Blast leakage pressures acting on a structure surrounding a protective cubicle were experimentally determined in a one-third scale model test. Nineteen pressure transducers were used to record the blast environment within the cubicle and on the surrounding structure. Variations in venting area were tested. Results indicate that the pressures can be sufficiently high to cause damage to conventional construction however, the pressures can be reduced to safe levels by restricting the venting. The velocity of secondary fragments produced from the breakup of simulated processing equipment subjected to the blast of full-size 81-mm mortars was determined. Photographic coverage and calculation of fragment penetration in backstops indicate heavy secondary fragments are capable of traveling considerable distances.
