Analysis and experiment of a vessels shell cover in submarine structureJournal of Marine Science and Application - Tập 3 - Trang 14-19 - 2004
Yu-li Zhang, Guang-wu Zeng
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 ... hiện toàn bộ
A review of the effect of a/W ratio on fracture toughness (I) —Experimental investigation in EPFMJournal of Marine Science and Application - Tập 4 - Trang 1-7 - 2005
Li Qing-fen, Jin Guo, Wang Yan-bo
Many experimental investigations have previously been performed and recently
done on different shipbuilding structural steels where the specimens size and
crack depth/specimen width (a/W) were varied. A series of interesting results
have been gained. It is worthwhile to have a review on the effect of a/W ratio
on fracture toughness, and further theoretical analysis is necessary. In this
paper, exp... hiện toàn bộ
Effect of Porosity on Oblique Wave Diffraction by Two Unequal Vertical Porous BarriersJournal of Marine Science and Application - Tập 18 - Trang 417-432 - 2019
Anjan Sasmal, Sandip Paul, Soumen De
The diffraction of obliquely incident wave by two unequal barriers with
different porosity in infinitely deep water is investigated by using
two-dimensional linearized potential theory. Reflection and transmission
coefficients are computed numerically using appropriate Galerkin approximations
for two partially immersed and two submerged barriers. The amount of energy
dissipation due to the permeab... hiện toàn bộ
Review of Ultimate Strength Assessment of Ageing and Damaged Ship StructuresJournal of Marine Science and Application - Tập 19 Số 4 - Trang 512-533 - 2020
M. Tekgoz, Y. Garbatov, C. Guedes Soares
AbstractThe 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 by accidental
loading or impact. ... hiện toàn bộ
Fatigue reliability of deck structures subjected to correlated crack growthJournal of Marine Science and Application - Tập 12 - Trang 413-421 - 2014
G. Q. Feng, Y. Garbatov, C. Guedes Soares
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... hiện toàn bộ
Emerging Challenges for Numerical Simulations of Quasi-Static Collision Experiments on Laser-Welded Thin-Walled Steel StructuresJournal of Marine Science and Application - Tập 19 - Trang 567-583 - 2020
Jani Romanoff, Mihkel Körgesaar, Heikki Remes
This paper re-evaluates recently published quasi-static tests on laser-welded
thin-walled steel structures in order to discuss the fundamental challenges in
collision simulations based on finite element analysis. Clamped square panels
were considered, with spherical indenter positioned at the mid-span of the
stiffeners and moved along this centerline in order to change the load-carrying
mechanism ... hiện toàn bộ
