| Description | A two-stage framework for: (1) deploying an appropriately spaced acoustic emission (AE) monitoring network using peizoelectric sensors coupled to steel structures within different soil-structure systems, and (2) then interpreting the measured AE data (in various parametric forms such as AE rates, b-values, frequency, etc.) using both absolute and rate based changes in time has been developed from a combination of computational (wave propagation within Disperse) and physical (shear box and large-scale) modelling experiments. |
| Exploitation Route | The development of an initial framework is a step towards the implementation and refinement of field-scale monitoring systems for monitoring the deterioration and general health of buried steel infrastructure systems (i.e. utility pipe networks, pile foundations). Further work refining the interpretation of results and expanding the potential uses of the system, such as with other infrastructure, as well as distinguishing between different AE generation sources would move the work forward more. |
