Computer Simulation of Ultimate Strength Degradation of Ship Structures by Corrosion and Fatigue

Current ship structure strength assessment procedures used by ship classification societies are mostly experience-based. The degradation effects of damages including fatigue, corrosion, collision and grounding on ultimate strength are seldom taken into account. Cui and Wu [1] proposed a more rational ship structure strength assessment method, First-Principle-Based Strength Assessment System (FB...

Probability Approach for Prediction of Pitting Corrosion Fatigue Life of Custom 450 Steel

In this study, the pitting type of corrosion growth characteristics, fatigue crack initiation and propagation behavior; axial fatigue tests were carried out on precipitation hardened martensitic Custom 450 steel in the air and 3.5wt% NaCl solution. Using the ratio of the depth to the half-width of the pits; (a/c)= 1.5±0.2 the corrosion pit depth growth law was obtained as a function of stress a...

Corrosion Protection Systems and Fatigue Corrosion in Offshore Wind Structures: Current Status and Future Perspectives

Concerns over reducing CO2 emissions associated with the burning of fossil fuels in combination with an increase in worldwide energy demands is leading to increased development of renewable energies such as wind. The installation of offshore wind power structures (OWS) is one of the most promising approaches for the production of renewable energy. However, corrosion and fatigue damage in marine...

Pitting corrosion and structural reliability of corroding RC structures: Experimental data and probabilistic analysis

A stochastic analysis is developed to assess the temporal and spatial variability of pitting corrosion on the reliability of corroding reinforced concrete (RC) structures. The structure considered herein is a singly reinforced RC beam with Y16 or Y27 reinforcing bars. Experimental data obtained from corrosion tests are used to characterise the probability distribution of pit depth. The RC beam ...
