The experiments aim to quantify early-stage micro-meso scale damage by measuring the nonlinear elastic response of the material.Experimental Configuration & Methodology: The setup consists of a high-power RF excitation and data acquisition system integrated with a precision mechanical alignment stage. <ul><li>Excitation & Amplification: A RITEC GA-2500A Gated RF Amplifier is used to generate high-power, gated RF burst signals. This allows for the excitation of finite-amplitude ultrasonic waves necessary to trigger nonlinear effects (e.g., second harmonic generation) in the metallic specimens.</li><li>Transducers: Broadband piezoelectric transducers (Olympus V-109, 5 MHz, 0.25 inch; V-110, 5 MHz, 0.5 inch) are employed for transmitting and receiving ultrasonic waves. The 5 MHz frequency is selected for optimal penetration and sensitivity to microstructural damage in metals.</li><li>Mechanical Alignment: A custom-built precision alignment stage, featuring manual X-Y-Z micrometer translation and a gimbal mount, ensures sub-millimeter accuracy in transducer positioning and acoustic coupling.</li><li>Data Acquisition: Ultrasonic waveforms are recorded using Tektronix MDO3024 and TDS 3014B oscilloscopes. High sampling rates (up to 2.5 GS/s) and deep memory (10M points) are utilized to capture the high-frequency harmonic content without aliasing.</li></ul>Data Contents: The dataset includes photographic documentation of the experimental setup, the ultrasonic transducers, and representative oscilloscope screenshots showing the excitation signals and received ultrasonic waveforms (including pulse-echo and through-transmission configurations). The dates on the oscilloscope screenshots (spanning December 2018 to June 2019) document the iterative development and testing phases of the experimental campaign. Significance: This experimental setup enables the precise measurement of nonlinear ultrasonic parameters, such as the acoustic nonlinearity parameter (β), which is highly sensitive to early-stage damage (e.g., dislocation substructures, micro-voids) in metallic materials. The data supports advanced structural health monitoring (SHM) and biomedical health monitoring applications.
