Modeling of acoustic-emission wave propagation in layered media
This study proposes a model for acoustic-emission (AE) wave propagation in a layered medium, which can be used for damage detection in structural health monitoring in general, and crack identification in non-destructive testing and evaluation for materials in particular. In the model, the materials are characterized by piecewise, layered media with one surface as free and the other as free, fixed or infinite. The AE waves are generated by dislocation over a fault area located in one of the layers or at a layer-to-layer interface. In this study, three-dimensional (3D) wave motion in each ...
