Failure Analysis is an engineering approach to determining how and why (cause and root cause) an equipment or a component has failed.
Failure analysis is a comprehensive investigation to determine failure mechanisms and root causes. It shows the differences between a component’s actual and requested profile. Through this methodology, conclusions are derived regarding the component’s behaviour in operation as well as remedial measures. The root cause analysis procedure involves collecting and analysing the data, developing appropriate corrective and/or preventive action, presenting the data clearly and generating a practical recommendation.
Failure analysis is the process of collecting and analyzing data to determine the cause of a failure, often with the goal of determining corrective actions or liability. The failure analysis process relies on collecting failed components for subsequent examination of the cause or causes of failure using a wide array of methods, especially microscopy, spectroscopy and Nondestructive Testing (NDT).
The failure analysis of different products involves use of the following tools and techniques:
Root cause analysis, including design, fabrication, transportation, installation and service
Examination of the parts to determine the failure mechanism(s)
Mechanical Testing & Chemical Analysis
Metallography (Optical Microscope)
Surface Analysis NDT (Visual, Dye Penetrant, Magnetic Particle)
