Statistical inference on progressive‐stress accelerated life testing for the logistic exponential distribution under progressive type‐II censoring

Quality and Reliability Engineering International, 2019
The accelerated life testing (ALT) is an efficient approach and has been used in several fields to obtain failure time data of test units in a much shorter time than testing at normal operating conditions.

Optimality in Accelerated Life Tests

Mathematics of Operations Research, 1992
We formulate a stochastic control problem arising from the optimal design of accelerated life tests. The model is obtained, in a natural way, in the setup of point processes. The cost functional depends on the total number of items under test at time t, the observed number of items failed up to time t, and the stress level applied to the items under ...

Accelerated cycle life testing and capacity degradation modeling of LiCoO2-graphite cells

Journal of Power Sources, 2019
Accelerated cycle life testing of lithium-ion batteries is conducted as a means to assess whether a battery will meet its life cycle requirements. This paper presents a study to identify optimal accelerated cycle testing conditions for LiCoO2-graphite ...

Accelerated life tests of ceramic capacitors

38th Electronics Components Conference 1988., Proceedings., 1988
Multilayer capacitors prepared from three different ceramics were tested under highly accelerated conditions of both voltage and temperature. Three types of breakdown were encountered: avalanche, fast thermal degradation, and diffusion or wearout. The goal was to determine whether data from highly accelerated life tests could be used to plot failure ...

Accelerated Life Tests and Information

Radiation Research, 1982
BARLOW, R. E. Accelerated Life Tests and Information. Radiat. Res. 90, 90-97 (1982). This is a partly philosophical discussion of the problems of conducting accelerated life test experiments and analyzing data from such experiments. The objective is to predict life at a specified stress level or radiation dose.

Estimation from Accelerated Life Tests

Technometrics, 1971
This study examines and develops new techniques for analyzing life test data. It obtains estimates for the life distribution in the use environment on based data from both the use and the accelerated environments. The techniques require only physically plausible assumptions, not the usual ones involving specification of a family of parametric ...

Accelerated Life Testing and Aging

2022
Abstract Accelerated life testing and aging methodologies are increasingly being used to generate engineering data for determining material property degradation and service life (or fitness for purpose) of plastic materials for hostile service conditions.

Development of Accelerated Life Test

2008 IEEE Conference on Robotics, Automation and Mechatronics, 2008
This paper summarizes the development of accelerated life test types, model, statistical method and its progress. To the mechatronic component whose failure mechanism is related to various operational stresses, the best way is to exploit variable stress accelerated life test (ALT), obtain the likelihood function with failure accumulative method, and ...

Agitation system accelerated life testing

2015 Annual Reliability and Maintainability Symposium (RAMS), 2015
Accelerated Life Testing (ALT) is an effective method of demonstrating and improving product reliability in applications where the product is expected to perform for a long period of time. ALT accelerates a given failure mode by testing at higher stress level(s) in excess of operational limits.
