摘要

Whether we are talking about a materials failure, a breakdown in a manufacturing process, a design insufficiency leading to a structural failure, or a combination of the above potential events, there are a number of techniques available for conducting as failure analysis. Sometimes the chosen material for a component does not withstand its ultimate environmental conditions to which it is exposed. Sometimes these materials were never tested under reasonable design conditions. Other times it may be that the part is exposed to conditions never intended for its service environment. Often, the materials used in a manufacturing process change over time. The vendor may often move their facilities (or owners) and/or manufactures the end product with different ingredients or percentages. In any case, the road to establish potential causes should be as thorough as possible.
