This paper presents a demonstration of a process and software for evaluating the ability of an electronic product to operate with out failure under anticipated life cycle loading conditions. For this purpose, a preliminary design for an electronic module that is being developed to support aircraft engines was selected and evaluated. The process included developing a model of the physical hardware, characterizing the anticipated operating conditions, performing load transformation, and conducting failure assessment. Results indicate that preliminary design would not meet design objectives and these results were confirmed by physical testing. As a result, design changes are being pursued to ensure a reliable product.
