A Technique for Accelerated Life Testing

Journal of Engineering for Industry, 1970
If it is assumed that test specimens fail as soon as the damage accumulated in them reaches some definite amount, then a simple accelerated testing technique can be devised. Some specimens are failed under uniform accelerated conditions, while others are foiled partly under normal conditions and partly under accelerated conditions, and a graphical ...

PLANNING FOR ACCELERATED LIFE TESTS

International Journal of Reliability, Quality and Safety Engineering, 1999
We present two alternative perspectives to the current way of planning for constant-stress accelerated life tests (CSALTs) and step-stress ALT (SSALT). In 3-stress CSALT, we consider test plans that not only optimize the stress levels but also optimize the sample allocation.

Testing of Hypotheses for Distributions in Accelerated Life Tests

Journal of the American Statistical Association, 1982
Abstract In this paper we consider the problem of inference from accelerated life tests in which a common parametric family of life distributions at the different stress levels is not specified in advance. By assuming a time transformation function, which is a version of the familiar inverse power law, we give a procedure for testing hypotheses that ...

Accelerated life tests for products of unequal size

IEEE Transactions on Reliability, 1996
This paper considers 'estimation of the lifetime distribution' and 'optimal design of constant-stress accelerated life test plans' for products of unequal size. The distribution is Weibull with a scale parameter that is a 'log-linear function of stress' and a 'power function of product size with a size-effect parameter'.

On the Life Prediction and Accelerated Testing of Solder Joints

Thermo-Mechanical Characterization of Evolving Packaging Materials and Structures, 1998
Abstract A critical review of the life prediction and accelerated testing of solder joints, including the role of constitutive modeling and the factors of accelerated testing, is presented in this paper. As a perfect example, Ford solder joint specimen was used to investigate accelerated testing factors under various accelerated testing ...

Challenges in accelerated life testing

The Ninth Intersociety Conference on Thermal and Thermomechanical Phenomena In Electronic Systems (IEEE Cat. No.04CH37543), 2004
Accelerated testing typically targets-life estimation and defect or design weakness identification. The intent is to obtain more information from a given test time than would normally be possible. Time compression is typically achieved by acceleration of single or combination of stresses- temperature, vibration, humidity, etc. Short product development

Bayesian Methods for Planning Accelerated Life Tests

Technometrics, 2006
This article describes Bayesian methods for accelerated life test planning with one accelerating variable, when the acceleration model is linear in the parameters, based on censored data from a log-location-scale distribution. We use a Bayesian criterion based on estimation precision of a distribution quantile at a specified use condition to find ...

Bayesian design for life tests and accelerated life tests

2018
This paper describes Bayesian methods for life test planning with Type II censored data from a Weibull distribution, when the Weibull shape parameter is given. We use conjugate prior distributions and criteria based on estimating a quantile of interest of the lifetime distribution. One criterion is based on a precision factor for a credibility interval

A model for accelerated life testing

Structural Safety, 1993
Abstract After a short motivation for the problem of extremely high reliability a nonparametric model for accelerated life testing is described. Besides well introduced classical models for high reliabilities are mentioned. Finally a stress-dependent model for crack growth based on fatigue accumulation is discussed.

An approach to accelerated life tests of electronic components

East-West Design & Test Symposium (EWDTS 2013), 2013
This article is devoted to the problems of conducting life tests of electronic components and to the ways of solving these problems. The need for research in the field of accelerated life tests is shown. A physics-of-failure approach to life tests with accent on parametric failures (due to aging) is considered.
