...Weiwei Yu; Dale G. Karr; Pedro M. Vargas Neuber’s theory of elastic and inelastic stress concentration factors are applied to the pit corrosion of plates. The finite element method is then employed to model the problem numerically and to calculate the stress concentration factors for semioblate...

..., is not addressed in fitness-for-service codes today. This paper presents nonlinear Finite Element Analysis (FEA) and full-scale 4-point-bend testing of pipes with locally-thinned-areas (LTAs) to simulate corrosion. The LTAs are loaded in compression, and the buckle moment is used as the carrying capacity...

.... This node has an effect only at the beginning of the calculation of future inspection plans: There is initial corrosion damage if there is “indication.” It is assumed that after each future inspection, coating protection is applied and no corrosion damage on the element remains. The probability tables...

...A. P. Shashikala; J. Ramasubramanian; G. Janakiraman The random nature of sea waves and the aggressive corrosive environment of seawater make corrosion an important factor in deciding the safe operational life of offshore steel structures. The consistent rise in offshore oil exploration activities...

...Daniel Straub; Michael Havbro Faber Many parameters influencing corrosion degradation are time variant and the corrosion process is thus subject to temporal variability, the real characteristics of which are commonly neglected in reliability assessment. After a short overview on the quantitative...

...Y. Garbatov; C. Guedes Soares; G. Wang The corrosion wastage of deck plates of ballast and cargo tanks is analyzed based on a nonlinear corrosion model. This model is able to describe an initial period without corrosion due to the presence of a corrosion protection system, a transition period...

...Ge Wang; John Spencer; Haihong Sun Damages to ships due to corrosion are very likely, and the likelihood increases with the aging of ships. Risk and reliability approaches are more and more frequently applied in design and maintenance planning. These advanced approaches require reliable data...

... facilitates a generic modeling of fatigue and corrosion degradation for both structural and process type components. Furthermore, special considerations are given to the important aspect of updating of inspection plans when degradation has been observed. The different aspects of RBI for steel components...
