Abstract

See full text

A method provides early estimation of product life using accelerated stress testing data. In an embodiment, data measured from a product operating in a first, high-stress environment is used to predict how long the product will operate in a second, normal operating environment before failure, using an exponential acceleration model. An additional feature of the present invention provides a quantified indication of how much the product has improved from a redesign.
