Measurement of Naval Ship Responses to Underwater Explosion Shock Loadings [PDF]

Shock and Vibration, 2003
The shock-resistance capability of battle ships against a non-contact underwater explosion (UNDEX) is a very critical factor of survivability. In July 1987 and April 2000, we successfully conducted UNDEX shock tests for a coastal mine hunter (MHC) and a ...
