Factors in a failure at the design stage
A failure analysis determines the initiation location(s), the mode of failure, and whether a material defect contributed to the failure. While these facts are important, the load or loads that generated the failure are just as, or even more important, to understanding and preventing future failures.
Test twice, manufacture once
During the design of most components, the expected loads are determined, and these are used to design the component. In actual applications, these loads are generally not well known, and can be significantly different than assumed in the design phase. Setting up and running a well controlled lab evaluation or simulation can lead to a much better understanding of the strength of the component, and if the assumed loading (during design) results in the same type of failure as occurred in service. In addition once the test is set up, improved designs can be evaluated much more quickly than in a field evaluation.
Eliminate product failure surprises
In most lab evaluations or simulations, the object is to break or generate a failure of the component or structure. However, often the evaluation or simulation results in an unexpected failure. A failure analysis performed on a lab generated failure can provide just as much insight into the performance of the component as the analysis of the field failure.
