  • Since the samples for some structural products are very few and the reliability obtained from the physical model has some errors, an integrated reliability function prediction model based on failure data, failure modes and degradation mechanics of the structural product is proposed. First order reliability method (FORM) is implemented to calculate the reliability based on physical model. Both the reliability from failure data and physical model are considered as fuzzy inputs to estimate the parameters in the probability distribution. The proposed reliability function prediction model can accurately predict the time-dependent reliability of the structural product. Reliability-based design and maintenance strategy can be properly made in terms of the predicted time-dependent reliability. An engineering example is used to illustrate the proposed reliability function prediction model.

Abstract: Since the samples for some structural products are very few and the reliability obtained from the physical model has some errors, an integrated reliability function prediction model based on failure data, failure modes and degradation mechanics of the structural product is proposed. First order reliability method (FORM) is implemented to calculate the reliability based on physical model. Both the reliability from failure data and physical model are considered as fuzzy inputs to estimate the parameters in the probability distribution. The proposed reliability function prediction model can accurately predict the time-dependent reliability of the structural product. Reliability-based design and maintenance strategy can be properly made in terms of the predicted time-dependent reliability. An engineering example is used to illustrate the proposed reliability function prediction model.
