Protection of electronics in submerged enclosures against underwater explosions
In the milieu of military sea mine design, it is often necessary to design mines that are to be placed at small distances from each other. A possible tactical purpose may require that each mine be set to explode at controlled instances in time without disturbing the operation of the other mines in …

The effects of underwater explosions on fish with techniques to mitigate those effects
… of environmental effects of underwater explosive use. The literature review demonstrated a lack of standardization of methodologies. A number of methodological questions were examined to determine how they affect the ability to compare published studies and the validity of …

Development of a Lung Surrogate Model for Assessing Biomechanical Responses to Underwater Explosions (UNDEX)
Underwater explosions (UNDEX) generate high-energy shock waves that pose significant risks to military personnel during training exercises and combat scenarios. The primary objective of this research is to develop a surrogate modeling framework using engineering materials to investigate the …

A Hybrid Framework of CFD Numerical Methods and its Application to the Simulation of Underwater Explosions
Underwater explosions (UNDEX) and a ship's vulnerability to them are problems of interest in early-stage ship design. A series of events occur sequentially in an UNDEX scenario in both the fluid and structural domains and these events happen over a wide range of time and spatial scales. Because of …

Damage Development in Static and Dynamic Deformations of Fiber-Reinforced Composite Plates
… composite's resistance to shock loads induced by underwater explosions has been delineated.

Assessment of LS-DYNA and Underwater Shock Analysis (USA) Tools for Modeling Far-Field Underwater Explosion Effects on Ships
… LS-DYNA and USA in modeling general far-field underwater explosions (UNDEX) by modeling a three-dimensional box barge that is subjected to a far-field underwater explosion. Past UNDEX models using these tools have not been validated by experiment and most are limited to very specific problems …

Computationally-effective Modeling of Far-field Underwater Explosion for Early-stage Surface Ship Design
The vulnerability of a ship to the impact of underwater explosions (UNDEX) and how to incorporate this factor into early-stage ship design is an important aspect in the ship survivability study. In this dissertation, attention is focused on the cost-efficient simulation of the ship response to a …

Empirical investigation of underwater blast
… effective placement. It should be noted that an underwater charge can be used in two distinctly different types of application against a target ' a large charge at a distance from the target (eg a torpedo) or a small charge in direct contact (eg demolition charge or limpet mine). In the first …
