Abstract:To use effectively various strength data of ceramic/metal joints for materials development, structural design, and strength reliability analysis in the future, fracture strength database was constructed by using commercial software of easy operativeness. The database has been collected the strength data of about 1800 or more obtained by bending, fatigue, creep, and heat cycle test, etc. It is equipped with the function of addition/edit and retrieval/extraction of data. Furthermore, as one of utilities of this database, a basic strength properties and strength reliability of joints were mentioned in this paper, and the unified strength estimation method was applied to the joints. As the results, an evaluation equations that were derived by considering scatter of joint strength, can estimate the strength that corresponds to various test situations from basic strength such as bending strength.
