Analysis and experiment of a vessels shell cover in submarine structure
Journal of Marine Science and Application - Tập 3 - Trang 14-19 - 2004
This paper aims to achieve analysis and experiment results that relate to mechanics capability and structural parameter of a special saddle shell of revolution. Theoretically speaking, the saddle shell of revolution consists of a toroidal shell and a spherical shell. The shells simultaneous equations can be solved with harmonious terms. Where, the fundamental equations can be solved by asymptotic ......
Review of Ultimate Strength Assessment of Ageing and Damaged Ship StructuresAbstract The objective of this work is to provide an overview of the ultimate strength assessment of ageing and damaged ship structures in the last decades. Particular attention is paid to the ultimate strength of plates, stiffened panels, box girders, and entire ship hull structures subjected to corrosion degradation, fatigue cracking, and mechanical damage caused ... ...

Fatigue reliability of deck structures subjected to correlated crack growth
Journal of Marine Science and Application - Tập 12 - Trang 413-421 - 2014
The objective of this work is to analyse fatigue reliability of deck structures subjected to correlated crack growth. The stress intensity factors of the correlated cracks are obtained by finite element analysis and based on which the geometry correction functions are derived. The Monte Carlo simulations are applied to predict the statistical descriptors of correlated cracks based on the Paris-Erd......
A Simplified Model for the Effect of Weld-Induced Residual Stresses on the Axial Ultimate Strength of Stiffened Plates
Journal of Marine Science and Application - Tập 17 - Trang 57-67 - 2018
The present work investigates the compressive axial ultimate strength of fillet-welded steel-plated ship structures subjected to uniaxial compression, in which the residual stresses in the welded plates are calculated by a thermo-elasto-plastic finite element analysis that is used to fit an idealized model of residual stress distribution. The numerical results of ultimate strength based on the sim......

Investigating the Effect of Geometric Shape on Air Cushion Lift Force
Journal of Marine Science and Application - - 2024
One of the crucial and challenging issues for researchers is presenting an appropriate approach to evaluate the aerodynamic characteristics of air cushion vehicles (ACVs) in terms of system design parameters. One of these issues includes introducing a suitable approach to analyze the effect of geometric shapes on the aerodynamic characteristics of ACVs. The main novelty of this paper lies in prese......

Review of research on interactions between deepwater steel catenary risers and soft clay seabeds
Journal of Marine Science and Application - Tập 8 - Trang 163-167 - 2009
Steel catenary risers (SCR) have become an enabling technology for deepwater environments. A comprehensive review was conducted on recent research that examined interactions between deepwater steel catenary risers and soft clay seabeds. This included the STRIDE (steel risers in deepwater environments) and CARISIMA (catenary riser soil interaction model for global riser analysis) joint jndustry jro......
The method of imbedded Lagrangian element to estimate wave power absorption by some submerged devices
Journal of Marine Science and Application - - 2014
A simple approach is described to estimate the wave power absorption potential of submerged devices known to cause wave focusing and flow enhancement. In particular, the presence of a flow-through power take-off (PTO) system, such as low-head turbines, can be accounted for. The wave radiation characteristics of an appropriately selected Lagrangian element (LE) in the fluid domain are first determi......
