Design and Analysis of Accelerated Tests for Mission Critical Reliability
CRC Press, Apr 27, 2004 - Business & Economics - 248 pages
Early approaches to accelerated testing were based on the assumption that there was a simple acceleration factor that would correspond to a linear scaling of time from the operating stress to the accelerating stress. This corresponds to the simplest physical model of the kinetics governing the underlying degradation, but this simple model does not
