Abstract: The concepts and contents of failure research are proposed.
The failure information, which included failure objects, failure
phenomena and failure environment, could be concluded into five kinds,
sixteen classes, and fifty-two species. It could be used to establish
failure diagnosis system to diagnose failure mode, reasons and
mechanism. It includes failure diagnose, failure forecast and failure
prevention in failure research. There are eight problem in failure
diagnose. These problems are diagnosing technology and way of fractures
and cracks, synthesis diagnosing technology and way of failure, quantify
diagnosing technology and way of failure, probability, faintness and
brainpower diagnosing technology and way of failure, environment
diagnosing technology and way of failure, material capability system and
token technology, counting testing and illation of stress technology and
way, simulating technology and way of failure. There are prediction and
prevention problems in failure prediction and failure prevention fields.
These ten problems are investigated from theory and practice in detail.
In last, the evaluative trend of failure research is pointed out.
