Special Issue Information
Dear Colleagues,
The diversity of metallic materials and applications under complex loadings, or in aggressive work environments, push the limits of material strength, as well as those of predictive models. Concerning metals’ resistance to fatigue crack growth, new manufacturing and microstructure architecturing possibilities might bring some improvement, which should be evaluated. Due to the possibility of structural integrity loss when fatigue cracks develop in materials, the ability to predict fatigue crack path and growth rate, even under non-proportional multiaxial loadings, at cryogenic or high temperatures, or in corrosive environments, remains a critical issue.
It is our pleasure to welcome contributions in the field of fatigue crack growth in metals. All approaches will be considered, including theoretical, numerical, and experimental techniques, with a special interest in papers wisely combining such approaches, or making clear connections between the metal microstructure and its resistance to fatigue crack growth.
Topics addressed in this Special Issue may include, but are not limited to:
- Fatigue crack paths in 3D, through heterogeneous, anisotropic or architectured microstructures;
- Analysis and simulation of fatigue crack growth mechanisms, crack tip plasticity and damage;
- Improvement of metals’ resistance to fatigue crack growth;
- Proportional or non-proportional mixed-mode I + II + III loadings;
- Bifurcation criteria and crack path prediction;
- Influence of non-singular stresses (T stress or normal compression) and residual stresses;
- Crack closure effects, crack face friction and wear, effective stress intensity factors;
- Measurement and inverse analysis of the displacement and strain fields near a crack tip;
- Influence of temperature and environment (including hydrogen) on fatigue crack growth in metals;
- Advanced experimental techniques applied to fatigue crack growth: X-ray tomography, in situ tests, digital image correlation, interferometric methods, original or coupled testing devices, etc.

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.
