Abstract:
In accordance with the present disclosure, a method of using acoustic emission data to predict the state of a structural element is described. The method includes capturing acoustic emission data for a structural element. The method further includes predicting the future stress intensity in the structural element using the captured acoustic emission data and calculating the probability of future failure of the structural element using the predicted future stress intensity.
