Subject: Accelerated testing Book
If anyone knows any good book on Accelerated testing then please suggest. Basically I want to understand how to isolate failure mode, mechanisms and then apply accelerated testing with allowable margins.

"Accelerated Life Models, Modeling and Statistical Analysis," by V. Bagdonavicius and M. Nikulin, Chapman and Hall, 2002 contains just what the title says, more than you ever wanted to know.
I need it though, because a client has done some step-stress testing, Miner's rule definitely doesn't suit, and higher stress levels do damage that causes later failure at lower stresses! Furthermore, life distribution under stress isn't Weibull, there may be thresholds, and there are two accelerated failure modes. The MTBF is accelerated about 1,000,000 times at highest stress level, and they want an MTBF estimate at working stress. The book helped me analyzed HALT data.
The book contains martingale theory and applications, as well as Cox relative risk (aka proportional hazards) models. Sure, it's an academic statistical text, but sometimes we have to stretch to use academic results. Cox RR model is widely used in biostatistics for clinical trials.
