A Review of Fatigue Crack Growth for Pipeline Steels Exposed to Hydrogen
Hydrogen pipeline systems offer an economical means of storing and transporting energy in the form of hydrogen gas. Pipelines can be used to transport hydrogen that has been generated at solar and wind farms to and from salt cavern storage locations. In addition, pipeline transportation systems will be essential before widespread hydrogen fuel cell vehicle technology becomes a reality. Since hy...
متن کاملAssessing and modelling the uncertainty in fatigue crack growth in structural steels
The prediction of the fatigue life of steel structures can be carried out in a number of different ways. A common method at the design stage is to use the so-called S-N approach using design data from a standard such as BS 7910. However, for existing structures containing defects of a known or postulated size, a fatigue life assessment is generally carried out using fracture mechanics. In keepi...
متن کاملSensitivity Analysis of Fatigue Crack Growth Model for API Steels in Gaseous Hydrogen
A model to predict fatigue crack growth of API pipeline steels in high pressure gaseous hydrogen has been developed and is presented elsewhere. The model currently has several parameters that must be calibrated for each pipeline steel of interest. This work provides a sensitivity analysis of the model parameters in order to provide (a) insight to the underlying mathematical and mechanistic aspe...
متن کاملModeling of Corrosion-Fatigue Crack Growth Rate Based on Least Square Support Vector Machine Technique
Understanding crack growth behavior in engineering components subjected to cyclic fatigue loadings is necessary for design and maintenance purpose. Fatigue crack growth (FCG) rate strongly depends on the applied loading characteristics in a nonlinear manner, and when the mechanical loadings combine with environmental attacks, this dependency will be more complicated. Since, the experimental inv...
متن کاملHigh-temperature Fatigue Crack Growth Behavior of 17-4 Ph Stainless Steels
The fatigue crack growth (FCG) behavior was investigated for 17-4 PH stainless steels in three heat-treated conditions, i.e., unaged (Condition A), peak-aged (Condition H900), and overaged (Condition H1150), at temperatures ranging from 300 to 500 C. The high-temperature fatigue crack growth rates (FCGRs) of Condition H1150 were increased with an increase in temperature. However, for Conditions...
