This paper discusses statistical inference and optimal design of constant-stress accelerated life testing for the Chen distribution under progressive Type-II censoring. The scale parameter is assumed to be a logarithmic linear function stress level. maximum likelihood estimates parameters are obtained. Then, observed Fisher information matrix derived utilized construct asymptotic confidence int...

Permanent deformation (rutting) is one of the typical failure modes asphalt pavement with a semirigid base in high-temperature areas. To address issues structure and remaining life prediction, method combining accelerated testing finite element (FE) simulation was proposed. A modified Burgers model considering creep parameter damage obtained using strain monitoring data laboratory test values, ...

To design against premature mechanical failure, most implant devices such as coronary and endovascular stents are assessed on the basis of survival, i.e., if a fatigue life of 10(8) cycles is required, testing is performed to ascertain whether the device will survive 10(8) cycles under accelerated in vitro loading conditions. This is a far from satisfactory approach as the safety factors, which...

The failure-time data analysis and testing methods are unsuitable for reliability analysis of such highly reliable products. Degradation data can particularly in applications in which few or no failures are expected, provide considerably more reliability information than would be available from traditional censored failure-time data. High – power white light – emitting diodes (HPWLEDs) have att...
