A management system on fatigue and fracture reliability database is developed for Chinese engineering materials. Considering extensibility, maintainability, reliability, safety, economy, and convenient usage, the system was established on a basis of combining technologies of IIS+ASP.NET +ADO.NET+SQL Server. Seven sub-databases were included. Main contents consist of probabilistic fatigue constitutions, fatigue strengths, strength-life curves, strain strength-life curves, cracking thresholds, fracture roughness values, and fatigue crack growth rates. Three searching ways are provided respectively by material name, chemical compositions, and mechanical properties. Perfect information for the seven sub-databases has been derived to benefit the wide applications for practice.
