Experimental Dataset of PMMA Vibration and Temperature Measurements Using laser Doppler vibrometry and IR Imaging under High-Power Ultrasonic Excitation

This dataset contains raw experimental data of vibration and temperature measurements on polymethyl methacrylate (PMMA) samples subjected to high-power ultrasonic excitation. Vibration data were acquired using a laser Doppler vibrometer (LDV), and surface temperature fields were recorded with an infrared (IR) camera. The dataset includes measurements on three PMMA samples. The objective of this study was to develop a rapid, non-contact method to determine the storage modulus master curve of PMMA, using laser Doppler vibrometry and high-power ultrasonic excitation. The data were used in the publication:Navid Hasheminejad and Nasser Ghaderi, "Rapid characterization of polymethyl methacrylate (PMMA) storage modulus using laser Doppler vibrometry and high-power ultrasonic excitation.", Measurement 253 (2025): 117543.https://doi.org/10.1016/j.measurement.2025.117543 All files are provided in MATLAB ".mat" format. A README file is included that describes the folder structure, variables, and data contents.
