The accelerated life testing is used to quickly demonstrate the ability of a product to perform its role, by increasing the stress conditions compared to those of its operational life. This educational book on the implementation of accelerated life testing therefore explains its theoretical foundations and offers a practical application guide which covers state-of-the-art thinking on design techniques and optimal planning of tests.
The application of accelerated testing theory is a difficult proposition, yet one that can result in considerable time and cost savings, as well as increasing a product's useful life. In Accelerated Testing: A Practitioner's Guide to Accelerated and Reliability Testing, readers are exposed to the latest, most practical knowledge available in this dynamic and important discipline. Authors Bryan Dodson and Harry Schwab draw on their considerable experience in the field to present comprehensive, insightful views in this book. Development and quality assurance tests are defined in detail and are presented from a practical viewpoint. Included are testing fundamentals, plans and models, and equipment and methods most commonly used in accelerated testing. Individuals seeking to evaluate and improve the design lives of components and systems will find this book a valuable reference, with special attention being paid to testing in the mobility industries.
A high percentage of defense systems fail to meet their reliability requirements. This is a serious problem for the U.S. Department of Defense (DOD), as well as the nation. Those systems are not only less likely to successfully carry out their intended missions, but they also could endanger the lives of the operators. Furthermore, reliability failures discovered after deployment can result in costly and strategic delays and the need for expensive redesign, which often limits the tactical situations in which the system can be used. Finally, systems that fail to meet their reliability requirements are much more likely to need additional scheduled and unscheduled maintenance and to need more spare parts and possibly replacement systems, all of which can substantially increase the life-cycle costs of a system. Beginning in 2008, DOD undertook a concerted effort to raise the priority of reliability through greater use of design for reliability techniques, reliability growth testing, and formal reliability growth modeling, by both the contractors and DOD units. To this end, handbooks, guidances, and formal memoranda were revised or newly issued to reduce the frequency of reliability deficiencies for defense systems in operational testing and the effects of those deficiencies. "Reliability Growth" evaluates these recent changes and, more generally, assesses how current DOD principles and practices could be modified to increase the likelihood that defense systems will satisfy their reliability requirements. This report examines changes to the reliability requirements for proposed systems; defines modern design and testing for reliability; discusses the contractor's role in reliability testing; and summarizes the current state of formal reliability growth modeling. The recommendations of "Reliability Growth" will improve the reliability of defense systems and protect the health of the valuable personnel who operate them.

Electrical Engineering Accelerated Stress Testing Handbook Guide for Achieving Quality Products As we move closer to a genuinely global economy, the pressure to develop highly reliable products on ever-tighter schedules will increase. Part of a designer's "toolbox" for achieving product reliability in a compressed time frame should be a set of best practices for utilizing accelerated stress testing (AST). The Accelerated Stress Testing Handbook delineates a core set of AST practices as part of an overall methodology for enhancing hardware product reliability. The techniques presented will teach readers to identify design deficiencies and problems with component quality or manufacturing processes early in the product's life, and then to take corrective action as quickly as possible. A wide array of case studies gleaned from leading practitioners of AST supplement the theory and methodology, which will provide the reader with a more concrete idea of how AST truly enhances quality in a reduced time frame. Important topics covered include: * Theoretical basis for AST * General AST best practices * AST design and manufacturing processes * AST equipment and techniques * AST process safety qualification In this handbook, AST cases studies demonstrate thermal, vibration, electrical, and liquid stress application; failure mode analysis; and corrective action techniques.
