Special Issue Information
Dear Colleagues,
In the context of the industrial design process, the reliable assessment of fatigue behavior is still a major concern for engineers, since the fatigue phenomenon tends to cause sudden and unexpected failures in engineering structures. In particular, these concerns apply to welded joints, where the presence of residual stresses and local severe stress/strain concentrations significantly affects the material behavior under cyclic loading. In spite of these challenges, most structural applications require the introduction of welded joints. Furthermore, in combination with other manufacturing technologies, welding processes are constantly advancing to meet industrial needs and expectations. In this context, fatigue design concepts are widely investigated, allowing them to continue to evolve and improve alongside welding processes and engineering structures.
The aim of this Special Issue is to provide an update in relation to state-of-the-art approaches for the fatigue assessment of metal welded joints. The topics that are of particular interest for this Special Issue are as follows:
- Fatigue strength of hybrid joints or joints between dissimilar materials;
- Fatigue strength of welded joints between Additively Manufactured (AM) parts;
- Fatigue strength of parts manufactured by Wire Arc Additive Manufacturing (WAMM);
- Fatigue strength of joints obtained by solid state welding;
- Applications to full-scale structures and industrial details;
- Criteria for fatigue assessment of welded joints under complex loading conditions, such as multiaxial constants and variable/random fatigue loadings;
- Effect of residual stresses on the fatigue strength;
- Post-welding treatments to enhance the fatigue strength of joints.

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.
