Cure rate based step-stress model
WebAug 1, 2014 · Tang et al. (2012) investigated the optimum design for the k-step-stress ALT for the twoparameter Weibull distribution based on the tampered failure rate model. Webexample, what is the stress needed to produce a minimum strain rate of 10-6 m/m / h ( or 10-2 m/m in 10,000 h) or what is the stress needed to produce a minimum strain rate of 10-7 m/m / h ( or 10-2 m/m in 100,000 h). An Arrhenius-type rate model is used to include the effect of temperature in the model of Eq. 8.6 such that: ε ˙ ss = ε ...
