European Network of Surface and Prestress Engineering and Design (ENSPED)

Objective



This project is the second step (implementation phase) of the project BRRT-CT97-0055. This project emphasises building a bridge between the fields of surface modification and prestressed processing in material engineering and CAD in mechanical engineering to find an appropriate way to approach to this interdisciplinary area. This network shall concentrated on the field of prestress processing. The objective of this project is to develop a global approach to use surface modification and prestressing for controlling and optimising important mechanical properties such as fatigue, wear and stress corrosion cracking. As applications, we can mention: composites, thermal sprayed coating, heat treatment and thermochemical processing (quenching, carburising, nitriding), mechanically treated surface (ultrasonic shot peening, shot peening), cold rolling, composites, etc.

This project explore the way to introduce the surface modification and prestress processing in the design of mechanical components and structures. In fact, the development of a global approach with associated CAD-CAM tool is necessary to link the engineers working in materials, design production and quality control. The residual stress consideration is becoming important today for two reasons: the necessity for the designer to reduce the weight of the structure and keep the same safety level to be competitive and the introduction of multimaterials which induces residual stress. With the development of different experimental and numerical techniques, it is now possible to introduce the residual stress in the design office for the integrated design of mechanical components. A new approach of concurrent engineering applied on the design of mechanical components with the residual and applied stresses consideration will be developed. 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. A 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.
