Dear friends,
as we embark on the first issue of 2025, I'm pleased to share a brief overview of FIS's activity throughout the past year.
In 2024, we received 446 submissions and published 85 papers, resulting in an 84% rejection rate (73% at desk). The average time to rejection was just one day, and the time from submission to acceptance decreased significantly from 69 days in January 2024 to 48 days in October 2024. We published four issues featuring authors from a diverse range of countries, with representation from 11 countries in the July issue to 19 countries in the April issue. Furthermore, 2024 saw the implementation of a new publishing schedule, enabling immediate paper publication upon acceptance of proofs and the uploading of Visual Abstracts.
All these results were possible only to a great community! We extend our sincere gratitude to the Editorial Boards, Reviewers, Section Editors, Guest Editors, and Authors for their invaluable contributions! The journal's success is a direct result of their dedication and effort.

We begin this new year with an important announcement. Since 2007, the journal has been registered with a dual title: "Frattura ed Integrità Strutturale" in Italian and "Fracture and Structural Integrity" in English. To enhance accessibility and searchability, we have decided to adopt the English title as the primary one. Therefore, starting with the January 2025 issue, the official title of our journal is "Fracture and Structural Integrity," with the Italian title as the “parallel”.

In this issue, we are excited to introduce a new initiative for our readers: Thematic Virtual Issues. Prestigious authors will delve into hot topics in the fields of fracture and structural integrity in a series of papers. Christos F. Markides and Stavros K. Kourkoulis from the National Technical University of Athens, Greece, prepared the first Virtual Thematic Issue, "Revisiting Classical Concepts of Linear Elastic Fracture Mechanics". We hope you enjoy this new offering!

Finally, mark your calendars for the upcoming joint conference organized by IGF: IGF28 - MedFract3 (https://www.igf28-medfract3.eu/).
This event combines the 28th International Conference on Fracture and Structural Integrity (IGF28) with the 3rd Mediterranean Conference on Fracture and Structural Integrity (MedFract3).
The conference will be held both in person in the beautiful setting of Aci Castello (Catania, Italy) and remotely. While remote participants will be able to fully engage in all sessions and discussions, they will unfortunately miss the opportunity to savor the delicious cuisine of Sicily!
The main deadlines are:
- Registration: always open
- Abstract Submission: 1.11.2024 to 31.05.2025
- Acceptance notification: 10.06.2025
- Early bird registration and payment: 31.07.2025
- Conference: 15.09.2025 - 18.09.2025
- Paper submission (after the conference): 15.10.2025
- Papers acceptance: 31.10.2025
