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!

Five different thematic symposia and a Summer School entitled “AI-Driven Innovations in Structural Integrity” are organized during the Conference.
It is important to underline that all fees collected will be entirely dedicated to::
• Event organisation;
• Summer School organization;
• Publication of the dedicated Procedia Structural Integrity issue;
• Publication of the IGF journal Fracture and Structural Integrity;
• All other IGF activities (e.g., website publication).
