| There exist a set of basic techniques for preventing failure in the design stage, and for diagnosing failure in manufacturing and later stages. |
|
It is quite commonplace today for design engineers to verify design stresses with finite element (FEA) packages. This is fine and good when FEA is applied appropriately. However, the popularity of finite element analysis can condition engineers to look just for red spots in simulation output, without really understanding the essence or funda at play.
By following basic rules of thumb, such danger points can often be anticipated and avoided without total reliance on computer simulation. | ||||||

In Post-Manufacturing Stages
|
Despite the best efforts of design and manufacturing engineers, unanticipated failure may occur in parts after design and manufacturing. In order for projects to succeed, these failures must be diagnosed and resolved quickly and effectively. Often, the failure is caused by a singular factor, rather than an involved collection of factors.
Such failures may be caught early in initial quality assurance testing, or later after the part is delivered to the customer. | ||||||
