A relational fatigue strength database system was developed on personal computer. The relational database management system FoxPro Ver 1. 0 was used, which is compatible with, and runs much faster than dBASE IV. The database system developed contains 545 S-N and 311 e-N curves. In addition, 280 fracture toughness data which are valid K e data according to ASTM standard are contained. Several application programs were also developed. Using the fatigue strength database system, approximation methods of e-N and S-N curves from material mechanical properties data were discussed. |
