Fatigue and Fracture Behavior of Materials: Multiscale Characterization and Computational Modeling

Dear Colleagues, 

This Special Issue focuses on advancements in the understanding of fatigue and fracture behavior in materials through the integration of multiscale experimental characterization and computational modeling. Given that engineering materials are increasingly being used in demanding environments, predicting their failure mechanisms has become critical for ensuring structural integrity and durability. This issue welcomes contributions that explore the fundamental and applied aspects of crack initiation and propagation, fatigue life prediction, and damage evolution across various material classes—from metals and composites to ceramics and polymers. Emphasis is placed on multiscale approaches, combining microscale observations (e.g., via SEM, X-ray CT, EBSD) with continuum and discrete modeling techniques, including finite element methods, cohesive zone models, phase-field approaches, and data-driven or machine learning-enhanced simulations. Special attention is given to the role of artificial intelligence in accelerating material behavior prediction, aiding inverse design, and improving model calibration across scales. By bridging scales and disciplines, this issue aims to foster innovation in the predictive modeling and experimental validation of material degradation phenomena, ultimately contributing to safer and more resilient engineering systems.

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 250 words) can be sent to the Editorial Office for assessment.

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.
