The samples were then nondestructively tested using nonlinear ultrasonics in the form of a non-collinear ultrasonic wave mixing approach. In addition, the test samples’ degradation of flexure strength due to damage accumulation caused by the exposure to increasing levels of temperature was also obtained using four-point bending tests. Results using the currently used non-collinear ultrasonic wave mixing approach correlate well (R2 = 92%) with the corresponding obtained reduction in strength, and with results obtained using different transducer arrangements.
