Failure Analysis and Preventions

There are various factors that could contribute to the failure of two adhered surfaces. Analyzing failures is a critical process in determining the physical root causes. The discipline of failure analysis has evolved and matured, as it has been employed and formalized as a means for failure prevention. Consistent with the recent trend toward increased accountability and responsibility, its purpose has been extended to include determining which party may be liable for losses, be they loss of production, property damage, injury, or fatality. The discipline has also been used effectively as a teaching tool for new or less experienced engineers. In the general sense of the word, a failure is defined as an undesirable event or condition. For the purposes of discussion related to failure analysis and prevention, it is a general term used to imply that a component is unable to adequately perform its intended function. The intended function of a component and therefore the definition of failure may range greatly. For instance, discoloration of an architectural feature is a failure of its intended aesthetic function. Failure can be defined on several different levels. The simplest form of a failure is a system or component that operates, but does not perform its intended function. This is considered a loss of function.

The prevention techniques have to be applied for a better functionality. The material has to be previously checked for failure tendencies and the process should apply for proposed conditions following to which an appropriate mitigation approach has to be done.
