Special Issue Information
Dear Colleagues,
In the context of the industrial design process, 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. These concerns especially apply to welded joints, where the presence of residual stresses and local severe stress/strain concentrations significantly affects material behavior under cyclic loading. In spite of these challenges, most structural applications require the introduction of welded joints. Furthermore, same as 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 to the state of the art on approaches for the fatigue assessment of metal welded joints. The topics which deserve particular interest for this Special Issue are applications to hybrid joints or joints between dissimilar materials; applications to full-scale structures and industrial details; criteria for fatigue assessment of welded joints under complex loading conditions, such as multiaxial constant, as well as variable/random fatigue loadings; the effect of residual stresses; and post-weld 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.
