In order to gain a competitive advantage in the world marketplace, Nordic industries need to press forward in several critical research areas. For cast load-carrying and work producing components and structures there is a need to integrate efficient FE based analysis tools, reliable information on defect size, shape and location, and expertise on how complex variable amplitude and multi-axial loading influence fatigue damage in cast materials.

The technical and scientific results of the Nordic R&D project “GJUTDESIGN-2005 - Design Kvalitet och NDT för gjutna utmattningsbelastade komponenter” were reported in a symposium 13-14 June 2005 in Helsinki Finland.

 


The project started in 2001 and involved 25 Nordic organisations from Sweden, Finland, Denmark and Iceland aiming to co-ordinate development of improved methods and tools for fatigue design of cast structures and components. The main objective was to improve the reliability and reduce the time and effort required to design complex fatigue loaded cast structures by developing design guidelines, quality rules and cost-effective NDE systems. Work on the project has proceeded simultaneously along several fronts such as fatigue testing of small test pieces and real components, application of different NDE-systems, modeling and analysis of complex structures, and quantitative examination of factors influencing cast quality. Important steps have been made in order to better implement fracture mechanics based fatigue assessment procedures for cast materials. Progress has been made in cast process modeling and control to avoid major defects and avoidance of chunky graphite that is often associated with high silicon iron. Several potential tools for reliable NDE have been investigated. The proceedings contain 30 reports and the majority of these will be presented in 7 sessions during the symposium. 



The impact of the project on the design of cast structures within the Nordic countries is significant. The participants are involved with most of the major Nordic companies where integrity of fatigue loaded cast structures is a design concern. The partners include 10 industrial companies that design and manufacture complex structures such as construction machinery, trucks, robots, windmills, paper machines and ship engines. The consortium also included five foundries, one engineering consulting firm, five research organisations and four universities. 



More than 50 individuals were involved in collaboration within this project, which has both maintained and strengthened Nordic networking between industry, universities and research organisations.
