RESPONSE OF STRUCTURES TO BLAST: A NEW CRITERION
NAVAL WEAPONS CENTER CHINA LAKE CA
Pagination or Media Count:
Distributed energy explosions and lumped energy explosions are examined in terms of two damage criteria currently in use 1 the peak overpressure and 2 the positive impulse per unit area. From these two diverse and partially contradicting items, the concept is developed that a suitable index for the damage potential of explosive blast is the impulse per unit area that it can deliver within some critical time.
