Comprehensive application of material database system in material selection evaluation

The material selection evaluation based on material database can bring database full play in the mass memory and the powerful search function, and can give computer full play in the supercomputing power. Since such, the old complex process, which is the selection of the evaluating material and mass data initialization and model calculation, becomes shortcut, exact, simple and intelligent. On the base of the material database system construction, the functional module of the material adaptability evaluation method was developed, and the computer aided selection evaluation of material based on the material database was realized. This is a beneficial try in the direction of the material database system intelligent development. The attained quantified evaluation results directly reflect the difference between the close property and different property of the material selection schemes. The subjectivity and blindness which are generated when the material selection is only based on the experience decrease.
