Time-To-Failure Models for Selected Failure Mechanisms in Mechanical Engineering,th of the materials. Important crystalline defects such as vacancies, dislocations, and grain boundaries are discussed. These crystalline defects can play critically important roles as time-to-failure models are developed for: creep, fatigue, crack propagation, thermal expansion mismatch, corrosion and stress-corrosion cracking.

Textbook 20101st editioneering po- tion, you will be asked — how long is your newly developed device expected to last? This text was designed to help you to answer this fundamentally important question. All materials and devices are expected to degrade with time, so it is very natural to ask — how long will the product las

Introduction, automobile tires) are fabricated from materials that will tend to degrade with time. The . will continue until some critical device parameter can no longer meet the required specification for proper device functionality. At this point, one usually says: the device has failed. This failure could be

Materials and Device Degradation,idence for degradation is apparently everywhere in nature. A fresh coating of paint on a house will eventually crack and peel. The finish on a new automobile will oxidize with time. The tight tolerances associated with finely meshed gears will deteriorate with time. The critical parameters associate

From Material/Device Degradation to Time-To-Failure,thods were presented in Chapter 2 which can be used for modeling the time-dependence of degradation. The question that we would like to address in this chapter is --- .? The time-to-failure equations are critically important, for device failure-mechanisms, and will be the focus of the remaining chap
