    Engineering Materials Database on Fuzzy Query

    • The fuzzy concept in nature language could not be expressed in current material databases.The method of matching of materials performance parameter and fuzzy sets and transforming nature language into SQL language was presented.Then an engineering material database which had fuzzy queries function was developed to turn fuzzy language into exactitude and judged queries condition in quantitative analysis way.An example of choosing material of crank in the database is given to validate the method.
