Material database

from Wikipedia, the free encyclopedia

Material databases are specialist databases for material selection . They offer the possibility of:

  • Storage of the material parameters obtained in a complex experiment
  • Provision of characteristic data and characteristic functions for selection, calculation and dimensioning for the purpose of safeguarding or reducing cost-intensive tests.

The possibilities of being able to access information on materials and to check the conformity of requirement and property profile have been significantly improved in recent years through the use of computer systems and the World Wide Web (WWW). Whereas in the past, specialist books, material suppliers and experts were often the only sources of information, the now created and steadily growing wealth of information and differentiated requirements (e.g. FE calculation) require electronic preparation, presentation and provision in the form of material databases. The data integrity (reliability), the continuous access to updated data stocks with the continuous inclusion of new and further developed material concepts for the safeguarding of product development processes are of great importance .

The main complexes are:

  • worldwide material comparison
  • mechanical properties (also temperature dependent)
  • physical properties (also temperature dependent),
  • technological behavior (e.g. joining , forming ),
  • application-specific behavior (e.g. corrosion),
  • chemical composition, material description, heat treatment and
  • Manufacturers, dealers / ranges, trade names

If a material database fits into the information philosophy of a specific company in a practical manner (e.g. knowledge management system for materials technology) and supports the designer, calculator, standard and buyer in their decisions using the material information and material selection profiles, then it also achieves the desired long-term acceptance.
