Abstract

A well-established materials property database did not provide adequate support for complex materials modeling. By recognizing the fundamental nature of experimental procedures, the current paper proposes a recursive hierarchical structure to provide a more flexible and uniform data model. By no longer concentrating on the differences between tests, the new data model allows the retrieval of the diverse, numerous, and complex experimental data that are necessary for complex materials modeling. The retrieval of any specific materials property occurs according to a query pattern that does not change dependent on the test type. Thus, analysis routines should be able to access directly the materials property database with a consistent method, enhancing the transparency of this aspect of the software.
