Failure Analysis Using Fractography

5 Applications of Fractography Failure Analysis Using Fractography 

From the preceding discussion, it should be obvious that ceramic failure in any practical application implies the existence of a flaw that degrades the strength below the theoretical value and a stress sufficiently high to propagate that flaw. The intent of the failure analysis is, usually, to determine the nature of the flaw and, if possible, to ascertain how it was introduced. It is also desirable to determine the magnitude of the stress and how the stress was generated.
