Profile

Luca Susmel, joined the University of Sheffield in July 2011 as Professor of Structural Integrity. Since 1998 Luca has focussed his attention mainly on problems related to the static and fatigue assessment of engineering materials and components. By working both in Italy (University of Padova, University of Ferrara, University of Udine), in Ireland (Trinity College, Dublin), and in the UK (University of Sheffield) he has devised several novel engineering methods suitable for designing notched and welded components against fatigue as well as against static failures. Luca’s modus operandi involves taking a conjoint theoretical and experimental approach to cracking problems and all the design methods he has formalised so far have been fully validated through systematic experimental work. Luca has a unique expertise in designing notched and welded components against constant and variable amplitude uniaxial/multiaxial fatigue. The work done in the above research areas has led to more than 130 scientific papers in the period 1999-2013 (of which 66 publications, according to Scopus, are in international peer-reviewed scientific journals) as well as to a book devoted to the multiaxial fatigue assessment. His scientific papers have attracted significant interest from the international scientific community, evidenced by an h-index of 16 with more than 700 citations in total according to Scopus. He is a member of the Editorial Boards of “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 has recently been appointed editor-in-chief of “Theoretical and Applied Fracture Mechanics”, Elsevier. Luca is a member of Commission XIII (Fatigue of Welded Joints) of the International

Research project(s)

Formalisation and validation a novel method to design notched components against fatigue

The ultimate aim of this PhD research work is the formalisation and validation of a novel method suitable for designing notched metallic components against proportional/non-proportional constant/variable amplitude multiaxial Fatigue. The above method will take as a starting point the assumption that the plane experiencing the maximum shear strain amplitude is...
