1. Overview of the consortium
The partnership of this network is composed by 4 universities which are leaders in Europe in different field of residual stress problems and 14 industries partners and industrial research centres which are major company in the field of aerospace industry, car industry, energy industry and mechanical industry. So the industry areas covered by the network is very large. The methodology developed can be extended to many SME which are suppliers company of above industrial sectors. The exchange between the industry peoples of different industry sectors will be very beneficial. The validation of research results carried out under real industry conditions can also initiate new research orientation. The work of this network is also very important for the future standardisation relative to residual stress problems. In fact, any standard exist in this field in Europe. At this moment, most industries use the US (ASTM, ASME) standards which are not really up-to-date with the research level of Europe in this area which is more advanced than in the US industries.
2. Profile of the individual partners
· For the "UNIVERSITE DE TECHNOLOGIE DE TROYES" (Project Coordinator), research in the field of residual stress, fatigue life prediction, and manufacturing process mechanical system design is a major research topic. About 25 people work in the above fields.
· CETIM, a technical research centre for about 7000 mechanical engineering companies in France has been working in the field of residual stress for 25 years and is one of the European industrial leaders in Europe with regard to the project topic.
· EADS, as a major aircraft manufacturer, is using residual stresses measurements more and more to improve the quality control of products ; it also wants to develop a global approach to taking residual stress into account.
· SNECMA is a major aircraft engine manufacturer in Europe and has many years of experience in the design of critical parts with residual stress problems.
· ABB is designing and manufacturing gas and steam turbines for industrial as well as power generation applications. The company wants to increase the knowledge of residual stresses, with respect to generation as well as measurement.
· VOLVO is an international transport equipment group producing trucks, buses, construction equipment, aircraft engines and marine & industrial power systems. Due to the demand of saving weight, surface modification of highly stressed parts is applied more and more. VOLVO is interested in an exchange of knowledge and experiences about residual stresses, especially measuring techniques, processes, simulations and lifetime predictions.
· STRESSTECH produces stress measurement equipment based on X-ray diffraction and micromagnetism. The participation in the proposed network will strengthen their competence and give many useful intereuropean contacts. Of the three areas of calculations, measurements and methods to create residual stresses, STRESSTECH is most interested in the area of measurements.
· WARTSILA NSD Corporation is a global engineering corporation focusing on power generation, marine and industrial markets. The company designs, produces, sells and services diesel and gas engines for transport and power generation.
· CENTRO RICERCHE FIAT (CR-Fiat) is involved in advanced interdisciplinary applied research regarding vehicles, engines, automotive electronic systems and processes/materials applications. CR-Fiat interest in residual stress field is focused on measurement techniques and on materials and surface/heat treatment processes applied to critical mechanical automotive components.
· SIEMENS/KWU is working on modelling (ADINA, ANSYS) as well as measuring (X-Ray, magnetic methods, ring-core-method) of residual stresses. Special surface treatments and welding techniques have been developed to introduce certain surface stresses.
· BAE SYSTEMS (Airbus) (BAe Airbus) is part of British Aerospace PLC which is the major aircraft manufacturer in the UK. BAe Airbus concentrates on design and manufacture related to Airbus Industry consortium aircraft employing about 5.000. It specialises in high efficiency wing structures an has responsibility for the design, manufacture and delivery of these parts to Airbus Industry of final assembly into their aircraft. The success of the operation depends on continuing R&T to maintain world class performance to survive competition from the USA. The deeper understanding of residual stress is one of the key areas in achieving these objectives.
· For LINKÖPING UNIVERSITY, DIVISION OF ENGINEERING MATERIALS, the origin and measurement of residual stresses (RS) is a major interest. RS due to machining, heat treatment and coating are studied, projects treat functionally graded materials, duplex strainless steels, nickelbase superalloys, aluminium alloys and steels.
· LTU is the abbreviated form of the Division of Computer Aided Design at Luleå University of Technology, Sweden. The staff of the division has been active in simulation manufacturing process such as welding, for more than a decade. The research that is of main interest for the proposed network is outlined below.
The competence in Simulation of Material Processing is based on computational thermomecanics, material and process modelling. The overall aim of the simulations is to compute residual stresses due to the manufacturing process and their influence on the subsequent use of components.
· INASMET is a Materials Research Centre developing activities such as R & D projects, either public, multiclient or public, technical assistance on materials (advisement, technical specification preparations, characterisation), and diffusion of the technologies. In these activities, INASMET is involved in three fields concerning materials : material obtention, materials use and environmental impact in manufacturing or using a product.
Regarding this project, the Characterisation Department will be responsible of their tasks. This department has broad experience on the subject, and well equipped laboratories, and being deeply involved in Research Programs, either European or National.
· SCANIA is a major truck manufacturer in Europe and has many years of experience in the design and production of critical parts, where the surface residual stress level is of vital importance. SCANIA uses residual stress measurement both in the product development process and as a quality control method.
· KASSEL University : mechanical surface treatments and residual stress analysis are main research areas of Institute für Werkstofftechnik/Kassel University since many years. In addition, consequences of near surface material, states for the fatigue behaviour is studied. X-ray as well as mechanical measuring methods are applied.
· ROBERT BOSCH GmbH is working worldwide mainly as an automotive supplier, with broad activities for example on power tools, automation technology and communications. High quality and performance of high stressed parts is realised and supported by residual stresses caused by heat treatment and/or shot peening.
· HYDRO ALUMINIUM AS is one of the largest aluminium companies in Europe, part of Norsk Hydro Group, Light Metal Division. It is an integrated company, with business oriented towards production of metal, semi an finished products and has several sub-division: Hydro Aluminium Metal Products, Hydro Aluminium Extrusion, Hydro Aluminium Rolled Products and Raufoss Hydro Automotive.
The company has a wide interest in acquiring the knowledge of residual stress and their management in the design.
