According　to　the　characteristics　of　ceramic　materials,　a　software　for　evaluation　of　brittle　material　mechanical　properties　was　developed　based　on　the　theoretical　and　experimental　research.　It　can　easily　calculated　and　evaluate　the　mechanical　properties　such　as　bending　strength,　local　strength,　elastic　modulus,　energy　dissipation　and　so　on.　It　also　has　the　functions　of　strength　evaluation,　thermal　stress　distribution,　lifetime　prediction　and　statistics　failure　analysis.　It　can　examine　and　evaluate　the　mechanical　properties　of　brittle　materials　more　conveniently,　more　accurately　and　more　easily,　as　a　tool　for　design　of　materials　and　structure.
