Special Issue Information
Dear Colleagues,
The current Special Issue will collect articles on the modern methods used in the analysis of the fracture process of metals and their alloys. The problem of accurate analysis of the cracking process is very important, and finding adequate solutions to it will allows us to understand the mechanisms of crack formation and development in structural elements made of metals. This, in turn, allows us to assess the strength of the elements at the design stage and after long-term service operation under high thermal influence, both in corrosive environments and with an active hydrogen. Analysis of the fracture process requires a comprehensive approach—conducting research using various methods aimed at achieving a common goal. Experimental research, specially when supplemented with metallographic tests of material microstructure and fractographic assessments of fracture surface, provides the information necessary to create numerical models. Calculations of mechanical field distributions, made during the simulation of the load of the tested specimens, allows us to determine the critical levels of stress and strain field characteristics—the stress triaxiality factor, the equivalent plastic strain, and the Lode factor. The comparison of the critical characteristics to those that occur in the tested elements will allow assessments of its current state and estimations of the remaining time of use. Nondestructive methods of testing—ultrasonic, acoustic emission, and others—also play an important role, allowing the identification of defects in structural elements and the tracking of their development during operation.
In this Special Issue, we welcome articles that comprehensively consider the problem of the cracking process of metal materials, as well as articles in which contemporary research methods for the individual stages of the fracture process are presented.

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.
