Summary

One basic requirement for any mechanical system is the reliability of operation. Thus, it is necessary to analyze and elucidate the possible mechanisms that lead to deterioration-failures during service. In order to determine and identify the causes that lead to the failure it is necessary to process some information, both about the previous stages of the design and processing, and about the fracture mechanisms and any relations concerning the structure and composition of the material. The paper describes a method to analyze and model the failures of the mechanical system. The model proposed uses an extensible tree taxonomy representation of failures that can be used as a mechanical failure oriented knowledge base.

The model allows the traversal of the failure tree in both ways, top-down or bottom-up. In a top-down tree traversal, when the failure is known (after it occurs), the causes of failures can be determined (to be removed), while bottom-up tree traversal allows the study of major failures (damages). An important issue of this knowledge base is its incremental development by refining of the knowledge in the existing nodes.
