ABSTRACT
Design of Experiments (DoE) is a means of obtaining quick, efficient, and accurate experimental data. DoE in combination with accelerated testing can facilitate reliability prediction in a relatively short time. About the only noncontroversial thing that can be said about accelerated testing is that it can be controversial. Accelerated testing is based on the fundamental principle that the unit under test will exhibit the same behavior in a short time at high stresses that it will exhibit in a longer time at lower stresses. Accelerated testing models include Mathematical models, empirical model, and Arrhenius Model. Properly understood and applied, acceleration models can help to understand, predict, and assure the reliability of a product during the design stage. Too often, however, they are not understood or applied properly, and serious mistakes can be made. Accelerated testing is useful for obtaining data for damage-endurance and tolerance-requirement failure mechanisms. It is not generally effective for stress-strength and challenge-response failures.
