Each paper presents unique perspectives on the issues facing test validation when evaluating graphite specimens with severe volume constraints.
Specifically, the papers have four principal objectives:
To collect evidence on test specimen size effects for a range of properties, test specimen geometries and test specimen volumes, with a view toward the collation of data in a single reference,
to provide a technical (theoretical and/or experimental) basis for restrictions on test specimen sizes specified or suggested by applicable ASTM standards,
to provide guidance on the number of tests necessary for a valid measure of a given property, and
to facilitate the development of new standards that will address emerging issues in graphite evaluations for specific applications.
With this publication you’ll gain knowledge from the UK-based researchers that present their valuable experience with their use of nuclear graphite. This is a comprehensive resource that includes past experimental and theoretical work, carried out by the UK nuclear industry, in addition to information about the current programs that are evaluating specific test techniques. Several papers analyze size effect issues that cover the mechanical, thermal, and physical property measurements and discuss using undersized specimens in these investigations. Other papers evaluate modeling and simulation considerations as well as existing data sets with limited populations.
