Principle:
The resonance frequency of a material depends on its shape, density, and elastic modulus. RUSPEC measures the ultrasonic resonance frequency of the sample material in an almost stress free state, iteratively matches and analyzes it with the resonance frequency calculated theoretically, and finally calculates the elastic modulus.
Place the sample between ultrasound transducers, minimizing the number of ultrasound transducers and minimizing external contact stress. When stimulated by ultrasound transducers, the sample will undergo normal vibration and obtain a series of resonance peaks, which depend on the size, shape, and elastic constant of the sample. Each resonance peak corresponds to a vibration mode.
