“…The USS Cole bombing caused 17 American sailors killed and 39 injured, the hull of the ship damaged seriously. Since then, a serious of experimental tests were conducted to investigate different materials and structures to enhance the blast protection of metal structures, the lightweight material with effective protection of structures attracts researchers' attention [2][3][4][5][6][7][8][9][10][11].…”

“…Under the blast loading, those protective coating will suffer large deformation in a short time, and the coating will absorb a large amount of shock energy due to its viscoelastic material properties [3,4]. Besides, the mismatch of the impedance between the coating and the hard substrate results in the shock wave continuously reflecting at the interface, and this will lead to the attenuation of the shock [5][6][7].Yong Chen et al [6] experimental investigated the blast resistance of rubber material coated on the floating structures subjected to underwater explosive loading. The results showed the elastomer would undergo a large deformation under shock loading, with absorbing a lot shock kinetic energy simultaneously.…”

“…The results showed the elastomer would undergo a large deformation under shock loading, with absorbing a lot shock kinetic energy simultaneously. In addition, they also researched the strong interaction between the underwater explosion and the soft coating [7]. It was found that coatings with high compressibility could reduce the intensity of shock waves by local cavitation, playing an important role in enhancing the blast resistance of steel structure during the shock wave loading.…”

Elastomeric material is used as blast-resistant structure because of its good mechanical properties.A series of underwater near-field explosive tests at different standoff distances were conducted to investigate the anti-explosion performance of steel structures covered with rubber and polyurea coatings. The experimental results demonstrated that both rubber and polyurea could enhance the blast resistance of test plates, and the polyurea coating performed better in reducing the deformation of steel plate and damage of steel structure. Compared with rubber, the polyurea has excellent mechanisms of energy absorption and dissipation, its mechanical behavior and molecular structure of elastomeric material determines the different ways of energy absorption and dissipation.

Abstract.A submersible vehicle mast is a device that extended above the surface of the water while the vehicle remains hidden below. Masts mounted above a submersible vehicle are used to support navigational instruments and various electronic devices, such as radar antennas and sensors. Submersible vehicle mast must be designed to survive extreme loading conditions, such as underwater explosions (UNDEX). The present study applied the finite element method, Cole's empirical formulation and acoustic-structure coupling method to simulate an UNDEX and investigate the survival capability of a damaged submersible vehicle mast. A shape optimization problem was solved for the submersible vehicle mast models subjected to UNDEX with different cross-sectional shapes are circle, ellipse and streamline shape, respectively. The submersible vehicle mast was modelled with cylindrical shapes. First, the cylindrical and rectangular plate in an UNDEX models were conducted and simulation results are close to the failure modes shown in experiments of Kwon and Ramajeyathilagam. Second, Three prototypes of submersible vehicle masts subjected to UNDEX were presented using the same method. The results were show the model with a circular cross-section is stronger than other designs when subjected to an UNDEX. The analytical results could offer a valuable reference for submersible vehicle mast design.

This paper focuses on the comparison between underwater explosion (UNDEX) shock loading empirical formulations. First, the numerical simulations for a cylindrical pressure hull subjected to UNDEX loading were conducted and the results are close to the failure modes shown in experiments of Kwon (1993). Second, the empirical UNDEX loading formula of Cole (1948), Keil (1961) and Shin (1994) used in cylinder subjected to underwater shock loading were compared. The simulation results by using three empirical formulas were compared and Shin’s (or Cole’s) empirical formula was shown to be better than the other empirical formulations when subjected to an UNDEX under the same conditions. The analytical results offer a valuable reference to the research of underwater explosion.
