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.

A Software Accelerated Life Testing Model

2010 IEEE 16th Pacific Rim International Symposium on Dependable Computing, 2010
Software system developed for a specific user under contract undergoes a period of testing by the user before acceptance. This is known as user acceptance testing and is useful to debug the software in the user's operational circumstance. In this paper we first present a simple non-homogeneous Poisson process (NHPP)-based software reliability model to ...

Optimal design of a simple step‐stress accelerated life test under progressive type I censoring with nonuniform durations for exponential lifetimes

Quality and Reliability Engineering International, 2019
Thanks to continuously advancing technology and manufacturing processes, the products and devices are becoming highly reliable. However, performing the life tests of these products at normal operating conditions becomes extremely difficult, if not ...

Accelerated Life Test and Life Prediction of an Electromechanical Actuator

2019 International Conference on Artificial Intelligence and Advanced Manufacturing (AIAM), 2019
This paper gives an accelerated test method for electromechanical actuator (EMA) and predicts its life based on Wiener process degradation model. According to the historical fault data and the FMECA analysis, we obtain that the key weak links of the electromechanical actuators are the electromagnetic clutch and the tachogenerator.

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.

Different estimation methods for exponentiated Rayleigh distribution under constant‐stress accelerated life test

Quality and Reliability Engineering International, 2018
The accelerated life testing 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.

On a bivariate accelerated life test

Journal of Statistical Planning and Inference, 1987
Consider a product which consists of two dependent components whose lifetimes follow the bivariate exponential distribution of \textit{H. W. Block} and \textit{A. P. Basu}, J. Amer. Statist. Assoc. 69, 1031-1037 (1974; Zbl 0299.62027). Maximum likelihood estimation of the parameters of the joint distribution of the lifetimes is discussed when the data ...
