Crack Growth Resistance of Structural Alloys

Dear Colleagues,

To reliably predict the lifetimes of products, it is necessary to know the properties of the materials from which they are made. Much attention of scientists from all over the world has been paid to establishing the relationship between the structures and properties of materials. One of the most important mechanical characteristics of materials is crack growth resistance. Crack growth resistance can characterize materials that operate under different types of loading, including static, cyclic, and dynamic loading.

A significant number of scientific works by the world’s leading scientists are devoted to the study of the influence of operating factors (high or low temperature, corrosive environment, radiation exposure, residual stresses, etc.) on the fracture micromechanism in materials of special purpose, since crack growth resistance is a structurally sensitive characteristic of materials.

It should also be noted that various imperfections and defects in materials may exist from the moment of manufacture, may arise during the processing of materials or the installation of the structural components, and may also develop during the operation of the structural components due to the action of various types of loads and environmental influences. Therefore, structural components can be fractured under loads that are significantly lower than the calculated ones, provided that the presence of such crack-like defects in the materials is not taken into account. Today, such calculations are increasingly based on the approaches of fracture mechanics of materials.

This Special Issue of Metals focuses on the crack growth resistance of structural materials as their structurally sensitive characteristic. The articles presented in this Special Issue describe the state of materials science in terms of crack growth resistance in 2022–2023 (see keywords/topics below). Your input on this topic is very valuable. We invite you to take part in research work that studies the influence of structures and structural imperfections on the properties (in particular, crack growth resistance) of structural materials, including those under the influence of various operational factors.

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.
