Special Issue Information
Dear Colleagues,
Additive manufacturing (AM) of metallic materials has emerged as a transformative technology, offering unparalleled design flexibility and enabling the fabrication of complex, lightweight structures. However, the long-term fatigue performance of AM metals remains a critical challenge, especially for safety-critical applications such as aerospace engines, gas turbines, and high-speed rail systems, where components are subjected to very-high-cycle fatigue (VHCF) loading (10⁷–10¹⁰ cycles).
In these environments, microstructural sensitivity and internal defects play a dominant role in crack initiation and growth, rendering traditional fatigue design theories centered around a fatigue limit of 10⁷ cycles inadequate. Furthermore, unique features such as defect-induced internal crack initiation, high variability in fatigue life, and the breakdown of conventional assumptions (e.g., material isotropy and stress intensity factor thresholds) require the development of new theoretical frameworks.
This Special Issue aims to highlight the urgent need to understand and model fatigue behavior in AM metals, particularly under long-term use. We invite contributions that explore the unique fatigue mechanisms in AM materials and propose novel experimental, theoretical, and computational approaches. Topics of interest include, but are not limited to, the following:
- Advanced characterization of defect-induced crack initiation.
- Multiscale and microstructure-sensitive modeling of fatigue behavior.
- Environmental and thermo-mechanical effects on long-life fatigue.
- Integration of machine learning and data-driven methods in fatigue life prediction.
- Statistical and probabilistic approaches to account for fatigue life scatter.
- Case studies and reliability assessments of AM components in real-world applications.
- Defect-tolerant design strategies for AM metals.
- In situ and operando fatigue testing with a focus on real-time fatigue monitoring.
- Fatigue of functionally graded and lattice AM structures.
- Fatigue performance of bioinspired AM metal components.
- Standardization and certification pathways for AM fatigue.
By addressing these challenges, this Special Issue seeks to pave the way for the reliable application of AM metallic materials in next-generation high-performance systems.

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.
