Failure is an undesirable and unacceptable event in the service life of a component or structure But in spite of the fact that utmost care is taken in the design and manufacture of components, many examples of service failures of engineering components are around us. While failures can be tolerated in non critical areas, where they would be more of an inconvenience, they cannot be allowed to occur in critical, high technology areas such as nuclear engineering, aerospace technology, power plants, etc. However, when such failures do occur, they provide an opportunity to identify deficiency areas and initiate remedial measures to prevent recurrence of the same. Failure analysis therefore provides the best tool for improving the reliability and safety of engineering components and structures. This article gives an overall view of failure analysis as a discipline and highlights NAL contribution in advancing the state of the art. The article is illustrated with numerous examples taken from case histories of failures and accidents investigated at NAL.
