Fundamental problems in blast-induced damage and protection of naval vessels: a state-of-the-art review

Large ships and submarines are the main equipment and mobile platforms supporting three-dimensional naval space operations. However, with the increasing damage power and strike accuracy of warheads, plus the diversity of destroying elements, their living environment is facing increasingly severe threats. It is thus necessary to work on the damage and protection of naval vessels subjected to blast loading. The blast-induced damage and protection of naval vessels is an interdisciplinary issue that involves the integration of explosion mechanics, fluid mechanics, structural mechanics, materials science and other disciplines in which many challenges are yet to be addressed. In view of some of the key issues involved, this paper systematically summarizes the research progress on blast load characteristics, damage mechanisms and protection technologies and equipment at home and abroad in recent years. The shortcomings of the current research are pointed out and the development trends of ship explosion damage and protection are predicted. This study can provide valuable references for future research on the efficient damage and protection of naval vessels.
