Piezoceramic-Based Damage Monitoring of Concrete Structure for Underwater Blasting
Sensors, 2020 This paper developed a piezoelectric-transducer-based damage detection of concrete materials after blasting. Two specimens (with or without an energy-relieving structure) were subjected to a 40 m deep-underwater blasting load in an underwater-explosion ...

Airblasts Generated by Underwater Explosions [PDF]
The Journal of the Acoustical Society of America, 1964 The pressure-time history of airblasts produced by deep underwater explosions is characterized by a fast-rising peak (P1), a broader second peak (P2), and a subsequent rarefaction phase (P3). P1 is traditionally associated with the least-time propagation path.

Analytical definition of parameters of pressure momentum of underwater explosion shock waves
Vojnotehnički Glasnik, 2001 A method for finding out the analytical expressions of pressure and the time of shock wave positive phase during underwater explosion has been defined as a function of explosive weight and the distance from the explosion center.

Airblasts from Shallow Underwater Explosions [PDF]
The Journal of the Acoustical Society of America, 1966 A shallow underwater explosion causes a supersonic plume to rise into the air. The plume shockwave produces the major peak in the ensuing airblast signature. An experimental investigation of the interaction between water motion and gas was conducted, wherein the parameters of the gas above the explosion were varied.

Fundamental Characteristics of Underwater Shock Wave due to Underwater Explosion of High Explosives.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1996 Fundamental characteristics of underwater shock waves generated by underwater explosion of high explosives are investigated by both experimentally and by numerical simulation. The attenuation process of the underwater shock wave is also investigated theoretically using a method of characteristics. Slab explosives are used in the experiments.
