Material databases are specialized databases for material selection
They offer the possibilities for
- Storage of the material parameters obtained in the course of extensive testing
- Provision of characteristic data and functions for selection, calculation and dimensioning for the purpose of safeguarding or reducing cost-intensive tests.
The possibilities of being able to access information for materials and to carry out a check of the correspondence between requirement and property profile have been significantly improved in recent years by the use of computer systems and the World Wide Web (WWW). Whereas in the past technical books, material suppliers and experts were often the only sources of information, the now created and constantly growing wealth of information as well as the differentiated requirements (e.g. FE calculation) require electronic processing, presentation and provision in the form of material databases.
A high priority is given to data integrity (reliability), continuous access to updated data inventories with the continuous inclusion of new and further developed material concepts for the safeguarding of product development processes.
Main complexes are
- global material comparison
- mechanical properties (also temperature-dependent)
- physical properties (also temperature-dependent),
- technological behaviour (e.g. joining, forming),
- application-specific behaviour (e.g. corrosion),
- chemical composition, material description, heat treatment and
- Manufacturers, distributors/assortments, trade names
If a materials database is integrated in a practical way into the information philosophy of a specific company (e.g. knowledge management system of materials engineering) and supports the designer, calculator, standardiser and purchaser in his decisions by means of the profiles material information and material selection, then it also achieves the desired long-term acceptance.
