Damage Monitoring in Brittle Rocks Using Nonlinear Ultrasonic
Confirmation seminar presented by Jiangwan He
Conventional strain-based methods for monitoring brittle fracturing in solids are destructive and often subjective. Nonlinear Ultrasonic Testing (NLUT) offers a promising alternative that is both non-destructive and more sensitive. While widely used in metals, its application in inherently highly anisotropic materials such as rock and concrete remains largely understudied. This project aims to perform a comparative assessment of the feasibility and accuracy of NLUT techniques in monitoring damage in brittle rock-like materials under various stress conditions, thereby improving the prediction of crack initiation and pre-empting potential unwanted failures in mines and tunnels.
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.
