An underwater explosion (also known as an UNDEX) is a chemical or nuclear explosion that occurs under the surface of a body of water. While useful in anti-ship and submarine warfare, underwater bombs are not as effective against coastal facilities.

2021年5月1日 · However, when subjected to under water explosions (UNDEX), navel composite structures experience highly nonlinear deformations and damages. Such transient deformation phenomena of composites and associated multiscale damages have been a …

2025年1月7日 · Researchers have achieved notable advancements over the years in exploring ship damage and stability resulting from underwater explosions (UNDEX). However, numerous challenges and open questions remain in this field.

Abstract: The Under Water Explosive Shock (UNDEX) test is an important step in certification for submarine service. It demonstrates the ability of a component or system to withstand a near by underwater explosion as may be encountered in a field …

2023年2月10日 · Underwater Explosion (UNDEX) is of hazardous consequence for both ships and submarines due to its prospective devastating effects on the combat capability of such seagoing platforms.

Abstract: Underwater explosion(UNDEX)will cause severe damage to ship structures and endanger the survivability and combat capability of the ship, which is a widely challenging problem in both academic and engineering fields. UNDEX loads include shock wave load and bubble load.

2015年12月1日 · When a ship is subjected to undex of dynamite explode under the near field of midship, the whole structure would be lethally damaged. As a result, the TNT is placed under the midship of the experiment model. The undex experiment with 55 g TNT put 0.2 m below 5# cabin was carried out in an airtight container, which is shown in Fig. 3. The actual ...

2011年5月12日 · This paper presents a brief introduction to the basic fundamentals of underwater explosions, including discussion of the features of explosive charge detonation, the formation and characterization...

概述了与导致结构瞬态动态加载的 undex 现象相关的特征事件。 远场 UNDEX 的载荷表征方法，基于已知重量和隔离距离的炸药对结构的入射压力载荷时间历史的经验计算。

ABAQUS capabilities for UNDEX (underwater explosion analysis) are integrated within the coupled fluid-solid interaction capability. Transient explosion simulations are generally handled in ABAQUS /Explicit, using specialized infinite boundary …
