STANAG 4142 Test Standard for Shock Resistance Analysis of Equipment for Surface Ships

EUROLAB laboratory provides testing and compliance services within the scope of STANAG 4142 standard. In combat operations, a warship may be subject to air blast and underwater shock loading, which, if detonated in close proximity to the ship, may cause damage to the ship, which may result in a dished ship for the hull plating or more severe perforation of the hull.

This research develops a procedure that combines the nonlinear finite element method with the double asymptotic approximation method and considers the effects of transient dynamic, nonlinear geometric, elastoplastic material behavior and fluid-structure interaction.

This paper addresses the problem of transient responses of a 2000 ton patrol boat subjected to an underwater explosion. KSF=0.8 was adopted to define the shock severity. Additionally, shock loading history, acceleration, velocity, and displacement time histories are presented along the spine.

In addition, the study explains the plastic zone spreading phenomenon of the ship and the deformation diagram. Knowledge of the ship's transient responses to underwater shock is useful in designing ship hulls to increase their resistance to underwater shock damage.
