Standards and Metadata Requirements for Computerization of Selected Mechanical Properties of Metallic Materials
Description: Abstract: To assist in building a computerized information system on the engineering properties of materials, the standards and metadata requirements for a representative group of mechanical property categories are considered. These categories include: tensile behavior, hardness numbers, notch-bar impact test parameters, and fatigue properties. For each property group, definitions of terms, synonyms (and non-synonyms), standard test methods, standards for reporting data, precision and accuracy, and correlations of properties are addressed. The principal findings and recommendations are as follows. Existing test methods are generally adequate for the properties considered, but better standards are needed for data reporting. Appraisal of materials variability and testing machine variability would be assisted by access to standard reference materials, certified as to their mechanical properties. All properties considered for inclusion in a computerized system can be categorized as parameters for direct search, parameters retrievable with extraction of all data stored for a given material, and parameters which are derived from an analytical representation of experimental data. Drafting of some general standards on computerized file structures and metadata files suitable for the engineering field is advised.
