This paper presents a benchmark study on the ultimate limit state analysis of stiffened plate structure subjected to uniaxial compressive loads, initiated and coordinated by ISSC 2022 technical committee III.1-Ultimate Strength. The overall objective is establish predictions buckling collapse strength structures loads. Participants were asked perform for full-scale reference experiment steel utilizing any combination class rules, guidelines, numerical approaches simulation procedures as they...
This paper presents a framework for structural analysis of icebreakers during ramming first-year ice ridges. The links the ice-ridge load and based on physical characteristics ship–ice-ridge interactions. A interaction study was conducted to demonstrate feasibility proposed framework. PC-2 icebreaker chosen ship–ice study, geometrical properties ridge were determined empirical data. modeled by solid elements equipped with continuous surface cap model (CSCM). To validate approach, simulated...
Inland river ships navigating in an ice area cannot avoid contact between the propeller and block. In addition to ensuring safety of blades, fatigue strength propulsion shaft system under load excitation must also be considered. This paper first studies how calculate natural frequency free torsional vibration system, then uses Newmark integral programing maximum stress at resonance speed. Low cycle high are studied according analysis theory. The method determining S–N curve spectrum is given...
Abstract DH36 steel is a widely used material in marine engineering. The fatigue crack propagation rates of at low temperatures have crucial influence on the strength structures operating polar environments. objective this paper to investigate behaviour (−60°C 20°C) by carrying out tensile tests and steel, order obtain steel. elastic modulus length measured compliance method considered. On basis Paris law, rate different investigated. results observed failure modes indicated that...
To address global challenges, research on the safety of polar navigation is indispensable. However, most studies focus traditional surface vessels, with few submarine. The dynamic response submarine during in floating ice channels under special conditions studied this work. Firstly, a model incorporating an intact internal frame was established. Subsequently, FEM-ALE coupled method employed to simulate structure-ice interaction, and obtained results verified by Colbourne method. Then,...
Welding defects are known to cause crack propagation and reduce structural fatigue performance. Based on the Paris theory of fracture mechanics, research is conducted evaluation methods for analyzing by adopting random loads with long-term distribution that follows Weibull stress ranges loads. This approach combined corrective intensity factor (SIF) equation method calculating reference failure criterion. A large container ship selected a simulation, analysis typical critical locations....
Abstract Compared to metal materials, composite materials possess favorable properties such as high strength-to-weight ratio and stiffness-to-weight ratio. They allow for a reduction in the overall weight of ship while still meeting requirements design, aligning with principles energy efficiency emission reduction. However, due anisotropy some components ships are easily damaged complex marine environment, which affects safety reliability entire hull structure. To understand ultimate...
As the development of polar region continues to increase, fatigue properties structures at low temperature are increasingly receiving researcher attention. This study aimed investigate T-welded and cruciform welded joints −60 °C. Logarithmic S–N curves based on hot-spot stress 50% 95% confidence levels were obtained The test results showed that almost 2–7% better than those Factors affected joints, such as concentration factor, microstructure, Vickers hardness profiles, fractography, also...
The study of the ultimate strength stiffened plates is a hot topic in ocean engineering. and behavior collapse were investigated using experimental numerical methods. Two plates, with one two half-bays both longitudinal transverse directions, tested under uniaxial compression. There clamped boundaries at ends panels restrained boundary on frames. novel three-dimensional laser scanning technology was used to measure initial geometric imperfections deformation after test. imported into finite...
