Statistical Ensemble Interactions in Microstructures where Damage Events Present

Abstract:

This work reports a study of the ensemble interactions in hierarchical structures where damage events present, a significant issue in the analysis of material failure. Our approach was data-enabled in which we constructed a multi-variate composing of the amplitude spectrum matrix of responses of the evolving hierarchical microstructure to the applied stress. The columns and rows of this matrix are vectors of the amplitude scale and the observation vectors of multiscale random damage events, respectively. The results showed that damage mechanisms occurred in ensemble clusters, and the multiscale random damage was strongly correlated in spacetime.
