An AGARD-coordinated corrosion fatigue cooperative testing programme

Abstract : The objectives of the programme are: to assess the effectiveness of state-of-the-art protection schemes for aluminium alloys with respect to corrosion fatigue and corrosion and fatigue; to stimulate the development of new protection products, procedures and techniques; to bring researchers on both sides of the Atlantic together in a common testing effort that would result in a better understanding of the corrosion fatigue phenomenon and the means of mitigating it for aerospace structural materials; to enable participating laboratories to add to their fatigue testing capabilities by using a controlled atmospheric corrosion environment. Within this context, a core programme was conceived as a two-phase programme of round-robin testing to establish whether participants could obtain confidence in one another's fatigue testing capabilities. At the same time the programme was designed to be sufficiently straightforward to encourage participation, particularly by those with relatively little experience of corrosion fatigue testing. This report is comprised of the programme manual and a description of the scope and purpose of the core programme, followed by presentation of the results, statistical analysis, discussion and conclusions. This Programme was sponsored by the Structures and Materials Panel of AGARD. (Author)
