This Research Topic is Volume II of a series. The previous volume can be found here: Design and Mechanical Failure of Deep-Sea Pressure Structures

Deep-sea pressure structures comprise an important and growing proportion of engineering construction, including submersibles, electronic cabins, underwater space stations, underwater robots, subsea pipelines and oil rigs. These structures are prone to instability in the case of hydrostatic pressure, which is significantly influenced by geometry, materials and defects. In extreme environments, deep-sea pressure structures can suffer from severe mechanical failures, including fatigue, fracture, creep, erosion and buckling. Furthermore, the synergistic effects of mechanical load, impact and corrosion (including but not limited to stress corrosion, erosion-corrosion, friction corrosion and corrosion fatigue) may lead to the quick failure of deep-sea pressure structures. As a result, the design of deep-sea pressure structures with excellent performance and the understanding of the failure mechanism of deep-sea pressure structures caused by mechanical damage are essential for the protection of deep-sea pressure structures.

Design and Mechanical Failure of Deep-Sea Pressure Structures will publish the latest research results and relevant information on all its related aspects, with special emphasis on damage evolution mechanisms and residual strength of deep-sea pressure shell structures, including residual stresses, corrosion fatigue, weld damage, crack extension and multi-crack coupling. Papers may be analytical, computational or experimental in nature. Meanwhile, researches on the assessment of the integrity and reliability of deep-sea pressure structures and the prediction and extension of their lifetimes are of interest and welcome.
