N2 - A novel approach is proposed for effectively estimating evolving damage state parameters using sensor data collected in real-time. The approach uses a state-space setting to formulate the progressive damage estimation in a Bayesian framework. The formulation consists of a damage evolution process (assumed Markov and obtained from fracture mechanics) and a measurement-damage relationship (based on hidden Markov modeling with joint time-frequency features). The damage state estimation is performed efficiently using sequential Monte Carlo techniques. In order to demonstrate the utility of the proposed method, results are presented for fatigue crack estimation for an aluminum CT sample subjected to variable-amplitude loading.
