205011 Acoustic emission monitoring of granite under bending and shear loading

Abstract:

In this study bending and shear fracture experiments on healthy and adhesively repaired granite samples with concurrent acoustic emission (AE) monitoring are discussed. AE can characterize the difference between the fracture modes using simple features analysis based on the activity of the early loading. It is the first time that such a direct correspondence between the stress field and the results of a monitoring technique emerge for granite. This offers new insight in the material's behavior especially in relation to complicated geometries where the dominant stress mode is not known a priori.
