Confirmation seminar presented by Arthur De Alwis.

Acoustic Emission (AE) sensors can be used to capture transient elastic waveforms produced by solid materials when stress states are changed. This technique has been widely used in fracture engineering to understand fracture propagation, initiation, and failure modes in rock-like brittle solids. However, the coupled effect of temperature and stress on waveform characteristics has been largely understudied. This study aims to establish a new framework to evaluate the thermomechanical effect of rock fracture using AE when catastrophic failures under thermo-mechanical coupling conditions are expected. The framework could be used to improve the understanding of deep mines and tunnels in which high geological stresses and large temperature gradients are commonly observed.

About Confirmation Seminars

The purpose of the confirmation milestone is to ensure that the candidate receives appropriate feedback in relation to the viability and progress of the thesis project and that the resources required to complete the program of research within the recommended timeframe are available. It is also an opportunity to ensure that the candidate has demonstrated the capacity and capability to successfully complete the thesis in a timely manner.
