Welcome to FESI


FESI - the UK Forum for Engineering Structural Integrity:
Working to assure the reliability, safety and economic viability of engineered systems, structures and components from design to end-of-life, and to reduce undesirable environmental impact.


FESI is the membership organisation for engineering structural integrity (ESI) in the UK. FESI disseminates the latest advances in ESI, promotes the exchange of ESI technologies and knowledge between industrial, regulatory, academic and professional organisations, encourages best practice in ESI, and provides a practical resource for anyone working in ESI. FESI aims to help improve the safe performance of and realise the economic potential inherent in the UK's engineering assets.

This is achieved through the organisation of CPD events, and the publication of a biannual journal, The FESI Bulletin, and textbooks through our wholly-owned subsidiary, EMAS publishing.

Increasingly, organisations are waking up to the fact that ESI's cross-industry, multi-disciplinary technologies, methodologies and practices underpin the success and safety of their current and future operations, although they may not, in the past, have regarded themselves as possessing an engineering component.

Sectors which recognise that ESI and the associated best practice makes a positive contribution to their survival range from the health, medical and healthcare industries, through architecture, construction, manufacturing, all branches of engineering and transport, to the renewable power generation, petrochemical, nuclear, and aerospace industries.

FESI's role as the UK's authority on ESI is supported and endorsed by a number of eminent and progressive organisations drawn from such sectors. These valued Sponsors acknowledge that the integration of ESI into their corporate policies has shown benefits for their development, operational safety, efficiency and sustainability. Sponsoring FESI is a way of helping to spread the positive message about ESI.

FESI is steered by a Council of distinguished ESI experts and specialists. See Who's Who in FESI.

Crack Initiation in Bearing Steels - 1 Day CPD Workshop

8 September 2015

Manchester Conference Centre, Sackville Street, Manchester, Uk

Download Flyer

Arising from the 2014 FESI seminar entitled “Advances in Rolling Bearing Fatigue”, emphasis on the mechanism of crack initiation around non-metallic inclusions in bearing steels was recommended, with particular attention being paid to the development of tensile stresses around inclusions that would accelerate crack initiation and growth. This seminar is informal and has the objective of stimulating discussions on the status of present research and the generation of ideas for future research. Non-metallic inclusions are believed to be the root cause of sub-surface initiated fatigue in rolling element bearings operated at stress levels typical of industrial machinery. The presence or absence of crack initiation and growth from inclusions (butterflies) is a likely explanation for infinite life observed in some applications. Clearly the mechanism for crack initiation, butterfly formation and micro-crack growth needs to be understood.

Who Should Attend
This Continuous Professional Development Workshop will be of interest to engineers, technology suppliers and academia working in the fields of rolling element bearings used in aerospace, automotive, marine systems, wind turbines, water turbines and other industrial machinery. The presentations will be given by practising engineers and academics experienced in this field.
