Failure analysis: techniques and few case studies

Engineering components are designed to perform a specafic function for a certain minimum period of time. Failures therefore, means its inability to perform its intended function. In spite of best effort, because of inherent uncertainty in design parameters and material behavior it is certainly impossible to avoid failure. A proper analysis of such case provides valu¬able insight into the mechanics of the process, identify the factors respon-siblefor failure and suggest necessary steps to be undertaken to overcome such incidents in future. Such studies have led to many innovations in de¬sign, development of new materials and process. The paper presents a broad overview of the tools and techniques used for such analysis.
