Dear friends,

IGF27, the 27th International Conference on Fracture and Structural Integrity, was a great success! More than 160 presentations, with more than 100 participants in presence and more than 70 in remote, allowed to organize a great event. Soon, the videorecordings of the presentations will be collected in a volume (with ISBN and DOI) and will be available in the IGF YouTube channel and in ESIS-PH (ESIS Publishing House) and a volume of papers will be published in Procedia Structural Integrity.

Now…let’s talk about the next IGF event:

The third European Conference on the Structural Integrity of Additively Manufactured Materials (ESIAM23)

The conference will be held in Porto (Portugal) an online in September 4-6, 2023 (www.esiam.site). The conference will provide an overview over current scientific knowledge and stimulate ideas for future research directions in this emerging field. Peer-reviewed contributions will be in the form of presentation or a poster. The agenda will allow for extended discussions and for exploring Porto at the end of summer. ESIAM23 is the third event of the ESIAM series following the success of the first event in Trondheim 2019 and the online conference held in 2021.

The abstract submission deadline is June 30, 2023 … join us!! Ciao!
