KEY BENEFITS INCLUDE:

Update yourself on the latest techniques for assessment of residual stresses from world-leading experts
Hear case studies from Industry and Academia featuring the latest tools and techniques
Understand how to improve performance in safety and structural integrity assessments and more accurately predict the lifespan of structures and components
Identify with leading experts the prediction, measurement and characterisation of residual stress

Overview

This event will reveal the variety of situations/industries and materials that residual stresses can occur in. Sharing of that knowledge across different sectors will allow cross-fertilisation of ideas of how to measure and control residual stresses, through discussion sessions.

Delegates will appreciate the range of industries affected by residual stresses and provide information on the latest techniques for the prediction, assessment and mitigation of residual stress. A special emphasis will be placed on the Materials industry where residual stress is a bi-product of composite production.

KEY TOPICS:

Structural integrity of nuclear manufacturing methods
Relaxation of weld residual stress during high temperature operation
ISO/TS 18166 Numerical welding simulation: Execution and documentation
Distributed internal strain measurement during composite manufacturing using optical fibre sensors
Thermal relaxation processes

WHO SHOULD ATTEND:

Mechanical engineering section head
Technical manager
Technical director
Chief engineer
Principal/Senior engineer
Design engineer
Structural engineer/ analyst

16:00 CHAIR’S CLOSING REMARKS

16:10 END OF SEMINAR

JOHN BOUCHARD: PROFESSOR OF MATERIALS IN ENERGY, THE OPEN UNIVERSITY

John Bouchard graduated in Mechanical Engineering (1976) and obtained an MSc in Physics of Materials (1977) at the University of Bristol. His first appointment for a Civil Engineering Consultancy broadened his engineering horizon before joining Rolls-Royce (1979) and specialising in stress and fracture analysis of rotating gas turbine components. From 1986 to 2008 he worked in the nuclear power generation industry in the field of structural integrity (supporting safety cases) and became recognised as the company residual stress expert. From 1995 onwards John initiated and managed many industry and EU funded structural integrity related research projects. In 2007 he was awarded a Royal Society Industry Fellowship and appointed Professor of Materials for Energy at the Open University in 2008.

SIMON QUINN: CHAIR STRUCTURAL TECHNOLOGY AND MATERIALS GROUP, INSTITUTION OF MECHANICAL ENGINEERS

Simon Quinn has been involved in the structural integrity field since his graduation. This has involved both numerical and experimental stress analysis work, as well as design. Since joining the RIfI, the industrial arm of the School of Engineering Sciences at the University of Southampton, in 2003, Simon has worked on more than 80 RIfI projects. For the previous four and a half years Simon was employed by NNC Limited, an engineering consultancy firm of approximately 1000 staff. Simon has an experimental/design background from research conducted using thermoelastic stress analysis (TSA) at the University of Liverpool.

SIMON SMITH: TECHNICAL MANAGER, TWI

Simon Smith completed doctoral studies on creep crack growth and then joined TWI in 1989. He is now the TWI Technology Manager of Numerical Modelling and a consultant in the TWI Integrity Management Group. The Numerical Modelling team have developed modelling methods for the fast and accurate assessment of the performance of welded structures, including the prediction of welding residual stresses, welding distortion and the determination of crack tip loading parameters for fatigue and fracture assessments.

MATTHIEU GRESIL: SCHOOL OF MATERIALS, UNIVERSITY OF MANCHESTER

Matthieu Gresil joined the School of Materials in February 2014 as Lecturer in Composite Materials, Non-Destructive Evaluation (NDE) and Structural Health Monitoring (SHM). He obtained his BSc degree in Physics (University of Nantes, France) and MSc degree in Physics option Matter and Materials (University of Nantes, France). He completed his PhD in Materials from Ecole Normale Superieure at Cachan, France in 2009 in collaboration with DCNS (French Navy) on the integration of functions (SHM and electromagnetic shielding) in composite materials. Then, he joined the University of South Carolina as Post-doctoral Research Fellow (2010-2014) and conducted research on SHM using multi-physics finite element to study guided wave propagation in composite and metallic structures.

COSTAS SOUTIS: DIRECTOR, AEROSPACE RESEARCH INSTITUTE, UNIVERSITY OF MANCHESTER

Costas Soutis has over 25 years of experience in working with composite structures and has made significant research contributions in modelling the compressive response of composite plates with open or filled holes under uniaxial, bi-axial static and fatigue loading; impact and post-impact compressive strength and crush energy absorption; multi-scale modelling of damage in orthotropic laminates under multi-axial in-plane loading; structural health monitoring using PZT activated Lamb waves and analysis and inspection of bonded patch repairs. Professor Soutis went on to become the first Professor of Aerospace Engineering at the University of Sheffield. In October 2012, he was appointed at the University of Manchester as Chair of Aerospace Engineering, Director of the Aerospace Research Institute and Director of the Northwest Composites Centre/National Composites Certification and Evaluation Facility.

CHRIS SUTCLIFFE: SENIOR LECTURER, CENTRE FOR MATERIALS AND STRUCTURES, UNIVERSITY OF LIVERPOOL

Chris Sutcliffe, works in additive manufacturing (AM) developing new processes and products. His work is patented, licensed and published worldwide and has resulted in the development of implants and manufacturing equipment. Active in manufacturing research since 1997 and a key player in 18 EPSRC, 10 TSB/DTi and 6 EU research projects he holds a tenured academic position at the University of Liverpool and is Research Director at Renishaw AMPD and Director and co-founder of Fusion Implants.
