Since 1998 Luca has focussed his attention mainly on problems related to the static and fatigue assessment of engineering materials and components. In particular, by working both in Italy (University of Padova, University of Ferrara, University of Udine) and in Ireland (Trinity College, Dublin), he has devised several novel engineering methods suitable for designing components (experiencing stress concentration phenomena of all kinds) against fatigue as well as against static failures. According to his modus operandi, Luca has performed both theoretical and experimental investigations and all the design methods he has formalised so far have always been validated through systematic experimental work. Luca has an outstanding and unique expertise in designing notched and welded components against constant and variable amplitude multiaxial fatigue.
The work done in the above research areas has led to more than 150 scientific papers in the period 1999-2019 (of which more than 130 publications in international peer-reviewed scientific journals) as well as to a book devoted to the multiaxial fatigue assessment (Susmel, L., Multiaxial Notch Fatigue: from nominal to local stress-strain quantities. Woodhead & CRC, Cambridge, UK, ISBN: 1 84569 582 8, March 2009). His scientific papers have attracted significant interest from the international scientific community, evidenced by an h-index of 29 with more than 2500 citations in total according to Scopus (h-index of 32 with more than 3600 citations according to Google Scholar). He is a member of the Editorial Boards of the two leading international journals in the fatigue and fracture field, namely “International Journal of Fatigue” and “Fatigue & Fracture of Engineering Materials & Structures”. Luca is also the Associate Editor of “Frattura ed Integrità Strutturale: The International Journal of the Italian Group of Fracture” (ISSN 1971-8993). Luca is the Editor-in-Chief of “Theoretical and Applied Fracture Mechanics” (published by Elsevier) which is one of the top journals in the fracture mechanics field (Impact Factor=2.215).
Luca has developed a software specifically designed to perform the fatigue assessment of plain/notched/welded components subjected to both constant and variable amplitude uniaxial/multiaxial fatigue loading (Copyright document N. 007849-D007048, released by SIAE – Società Italiana degli Autori ed Editori, www.siae.it).
