Special Issue Information

Dear Colleagues,

The twin disciplines of fatigue and fracture are central to a wide range of industries: aerospace, power generation, nuclear power, rail, bridge construction, and others. However, recent developments have resulted in breakthroughs in a number of areas, both in conventionally and additively manufactured metallic metals. Furthermore, with the move to digital twins, 3D printing, and the ability to build materials with properties that are tailored to specific applications, these developments have the potential to transform the disciplines of fatigue and fracture as well as national economies. The aim of this Special Issue is therefore to create a focal point whereby practitioners, engineers, and researchers can access these numerous exciting developments.

In this Special Issue, original research articles and reviews are welcome. Research areas may include, but are not limited to:

Damage Tolerance; durability; crystal plasticity; LEFM; fatigue crack growth; crack closure analysis and theory; additive manufacturing;  linear elastic fracture mechanics (LEFM); digital twins; computational mechanics; lead crack approaches (exponential crack growth); cold spray repair technology; cold spray additive manufacturing (CSAM); corrosion–fatigue interactions.

We look forward to receiving your contributions.

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.

This purpose of this paper is to examine the relationship between crack growth equations based on Elber’s original plastic wake induced crack closure concept and the fatigue threshold as defined by the American Society for Testing and Materials (ASTM) fatigue test standard ASTM E647-15el. It is shown that, for a number of conventionally manufactured metals, the function U(R), where R is the ratio of the minimum to maximum applied remote stress, that is used to relate the stress intensity factor ΔK to the effective stress intensity factor ΔKeff is inversely proportional to the fatigue threshold ΔKth(R). This finding also results in a simple closed form equation that relates the crack opening stress intensity factor Ko(R) to ΔK, Kmax, and the fatigue threshold terms ΔKth(R) and ΔKeff,th. It is also shown that plotting da/dN as function of ΔK/ΔKth(R) would appear to have the potential to help to identify the key fracture mechanics parameters that characterise the effect of test temperature on crack growth. As such, for conventionally manufactured metals, plotting da/dN as function of ΔK/ΔKth(R) would appear to be a useful addition to the tools available to assess the fracture mechanics parameters affecting crack growth.
