Further exploration on philosophical concepts and analyzing overlapping technologies of failure study

The epistemology, contradiction theory, system theory, methodology and their main points are briefly explained and summarized from the viewpoint of philosophy. The applications of philosophical concepts to failure accidents analysis, diagnosis and prevention are proposed, which establish the preliminary foundation for deepening the philosophical concepts of failure study. The theory and technology system of failure study is summarized from the aspects of theory foundation, application foundation and engineering technology, which provide a technology framework of failure study system construction. Some scientific problems or key technologies in the overlapping technologic field between materials science and engineering and failure study are summed up from the three stages, i.e., before service, in service and after failure. Further guidance on how to strengthen the research of overlapping technology is also proposed.
