Paper Abstract

The accurate estimation of fatigue life of metallic structural components in service environments is still a challenge for the aircraft designer or fleet manager. Majority of the current available fatigue life prediction models has deficiency to accurately predict damage under random or flight profile service loads. The inherent accuracy is due to the stochastic nature of crack propagation in metallic structure. In addition, currently no generic prediction model available accounting the load interaction effects due to variable loading. In the present paper we discus the use of a Generic Bayesian framework based Gaussian process approach to probabilistically predict the fatigue damage under complex random and flight profile loading.
