General Failure Analysis Procedure
Although the sequence and the steps may vary depending upon the character of
the failure, some of the steps that may comprise a typical failure
analysis are shown below:
- Collection of background data (review documentation and speak with
appropriate individuals)
- Selection of failed and unfailed samples for examination
- Preliminary examination of the failed part
- Nondestructive evaluation
- Mechanical testing
- Macroscopic examination and analysis
- Microscopic examination and analysis
- Determination of failure mode.
- Chemical analysis
- Fracture mechanics considerations
- Full scale testing under service conditions
- Analysis of the evidence
- Formulation of conclusions
- Recommendations to prevent reoccurrence
