Special Issue Information
Dear Colleagues,
The mechanisms of damage and failure of metals under mechanical or combined loads have been widely studied, and high strength materials have been developed. Nevertheless, under complex load conditions frequently occurring in technical applications, unexpected material behavior or failures still occur today. Under tribological loads, chemical and microstructural alterations occur in the material, and surface properties under cyclic and multiaxial stress fields are difficult to determine or predict. echniques of severe plastic deformation, on the other hand, allow the introduction of extremely high strains, typically by shear, without inducing defects through the superposition of hydrostatic compressive stress. Understanding microstructural mechanisms of damage and strain accumulation, but also healing effects through recovery or recrystallization, allows us to understand ways in which materials may be loaded well beyond their current range of application—or clarifies in which load situations conventional material properties will overestimate a material’s performance in a given load situation.
This Special Issue focuses on research aiming at the understanding of fundamental mechanisms of materials’ reactions to potentially damaging mechanical load conditions. This encompasses the analysis of microstructural mechanisms of defect accumulation, as well as studies into targeted measures to counteract or mitigate damage accumulation on a microstructural level. Full research articles, shorter communications reporting limited but conclusive studies of a specific topic, as well as reviews are welcome.

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. Materials is an international peer-reviewed open access semimonthly 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.
