“…Liu et al . observed that steel plates with front-face coatings had lower final deformation than those with back-face coatings (Liu et al. 2022 b ), illustrated in figure 7, and further research showed that dual-faced polyurea applications could be more effective than single-sided ones, illustrated in figure 8 (Liu et al.…”

Underwater explosions are inherently complex and unique physical phenomena markedly distinct from those occurring above the surface. This distinctiveness is primarily attributed to the relatively incompressible nature of water, which fundamentally alters the propagation and impact of shock waves. The study of underwater explosions is paramount in applications such as underwater demolitions for construction and salvage operations. These applications require a comprehensive understanding in order to mitigate the disturbances’ impact on marine structures and ecosystems. Studying underwater explosions and their mitigation encompasses various disciplines, including fluid mechanics, materials science and structural engineering. The work reviewed in this study contributes significantly to enhancing safety measures in marine structures by providing critical insights into the behaviour of structures under extreme conditions. This includes understanding the behaviour of gas bubbles formed by explosions, the transmission of shock waves through different media and the resultant forces exerted on structures submerged in water. Consequently, this review is meant to aid in designing robust and resilient marine systems capable of withstanding severe loading conditions caused by underwater explosions by providing key engineering considerations. The continuous evolution of this research area is essential for advancing maritime technology, ensuring the safety of undersea operations and protecting marine environments from the adverse effects of extreme subaqueous loadings.

“…The study indicated that using polyurea coatings considerably improved the bonding strength between steel and concrete, therefore boosting the overall performance of the concrete construction. In a study by J. Liu et al (2022) and Y. xiang Sun et al (2021), SEM was utilized to examine the influence of various polyurea coating types on the corrosion resistance of concrete [ 6 , 38 ]. Q. Liu, Guo et al (2021) and Hao Wang et al (2019) discovered that polyurea coatings with particular compounds enhanced the corrosion resistance of concrete.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
