Special Issue Information
Dear Colleagues,
This Special Issue of Metals, titled Fatigue Crack Propagation: Analysis of Safe Life Extension, is applicable to high-energy rotating disk components, pipelines, and/or other components operating under complex service conditions. Most components age upon utilization; therefore, there is a need to understand more fully the physics of ageing by testing representative components and modeling that behavior to be utilized in life extension analysis. The Special Issue will explore data generated on the components exposed to service conditions (aged materials) for one safe life or retired from service, thereafter used in the analysis to extend life if proven safe. The representative residual static and fatigue crack propagation behavior of high-performance materials used in aerospace, power, chemical plants, and other industries will be key in assessing life extension. New empirical models developed and used in the simulations to extend the safe initial life assume the given defect distribution, fretting, and corrosion damage, as well as damage developing from utilization in terms of scratches. Additional damage due to manufacturing and inspection will be added to estimate crack propagation and allowable risks. Risk assessment tools will be investigated to extend these components through additional one-safe life as economical benefits would be more significant than replacing the components and/or plants. The papers presented in this Special Issue give an account of the state of the art technology development. Your contribution to this issue will be highly valuable and appreciated and will define the future methods to be developed and used globally on this research.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
