Simuline Fatigue Course

May 29, 2017 – June 2, 2017

Designing plain, notched and welded metallic components against uniaxial/multiaxial constant/variable amplitude fatigue

Welcome to the Multi_FEAST fatigue short course, part of the Simuline family.  We are delighted to launch our new fatigue course aimed at the professional engineer. Whether you are looking for training as part of your continuing professional development, or you would like to bring yourself up to date with the latest multiaxial, weld and notch fatigue design methods, or you need training and support in using the Multi_FEAST software, we think that you will find something to interest you in our course.

Over the five day course, we build on the basic principles of fatigue and solid mechanics and guide you through the myriad of fatigue design and assessment methods.  You will learn about, and get practice in using tools to deal with notches, cracks, welds, variable amplitude and multiaxial loading.

We have developed this course to train and educate engineering practitioners. So you will not only learn about the background and theoretical basis of the many different fatigue tools, but you will develop your skills in using these methods, and in deciding which is the best approach to take to solve your particular problem.

The teaching philosophy we adopt is a little different to many other fatigue short courses, and is based on our longstanding experience as educators and researchers.  We build up your skills and confidence through a series of worked examples, tutorials and group case studies, supported by the lectures and feedback sessions.  Luca, Morris and John are your three tutors for the week and they will be on hand throughout to provide advice and guidance on all of the topics covered in the course.

We hope that you take a look at the details of the course on this site and we look forward to welcoming you to Sheffield in June.

 Luca Susmel’s Curriculum Vitae

lucaSince 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 any kind) 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 a 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 120 scientific papers in the period 1999-2016 (of which 95 publications, according to Scopus, 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 24 with 1600 citations in total according to Scopus. 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 a member of Commission XIII (Fatigue of Welded Joints) of the International Institute of Welding ( Luca is the Editor-in-Chief of “Theoretical and Applied Fracture Mechanics” (published by Elsevier) which is the top journal in the fracture mechanics field (Impact Factor=2.025).

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,

As to the transfer of his research’s outcomes into engineering practice, in recent years, and especially after the publication of his book, Luca’s expertise has been sought on many occasions by several structural engineering (working in both European and non-European companies) successfully using the approaches developed by Luca himself to design real components and structures.

John Yates’ Curriculum Vitae

johnJohn Yates studied Natural Sciences at Pembroke College Cambridge. It was here that his tutor G.C. Smith first interested John in fatigue as a subject of study. After a brief period at Cranfield studying fracture under Peter Hancock, John joined the University of Sheffield to study for a PhD where he was supervised by one of the great characters in fatigue, Keith Miller. This was in 1982, in what might be regarded by future historians, as the Golden Age of fatigue and structural integrity research at Sheffield. At that time there were three Fellows of the Royal Society: Bruce Bilby, Stephen Dugdale and Jock Eshelby; Mike Brown and Ian Howard were both young academics who went to get Personal Chairs; and Martin Goldthorpe and George Cardew were developing the finite element code, TOMECH, that was the first to really be able to perform fracture mechanics calculations. Rod Smith later joined the Department of Mechanical Engineering along with many illustrious visitors, such as Hong Youshi, Wei Yang and Alfredo Navarro who came to spend some time there.

John stayed at Sheffield until 2010, having been awarded a Personal Chair in 2000 and serving as Head of Department from 2004 until 2008. He joined the University of Manchester in 2010 until January 2014 as Professor of Computational Mechanics and Founding Director of the Modelling and Simulation Centre.

John is now an independent engineering consultant, specialising in fatigue, fracture and structural integrity and has maintained his commitment to education and training through his involvement with the Sheffield Fracture Mechanics course (

John is a Chartered Engineer and Fellow of the Institution of Mechanical Engineers. He is also a Higher Education Academy National Teaching Fellow and former Chair of the Editors of Fatigue and Fracture of Engineering Materials and Structures. John has published over 230 archived articles, including around 100 international peer reviewed journal papers, supervised more than 20 PhD graduates and examined 23 doctoral students in the UK, France, Holland and Spain.
