Abstract:

In many situations where the amount of time available for testing is considerably less than the expected lifetime of the component, we often use accelerated life-testing. To translate test results obtained under accelerated conditions to normal using conditions, the “Maxwell Distribution Law “can be used. In this paper, a combined approach of a sequential life testing and an accelerated life testing is applied to a low alloy high-strength steel component. The underlying sampling distributions are assumed to be three-parameter Weibull and Inverse Weibull models and a linear acceleration is employed. To estimate the three parameters of both models, we use a maximum likelihood approach for censored failure data and apply truncation mechanisms developed by De Souza [1] for both models. An example illustrates the application of this procedure.
