Abstract
This work approaches the elastic properties of non-piezoelectric materials and reports their temperature dependence for a duraluminum substrate. The method is based on the propagation time measurement of ultrasonic Rayleigh waves and attenuation of electrical voltage between emitter and receiver. Transducers made of P(VDF-TrFE) polymer film are used for Surface Acoustic Waves (SAW) generation and detection
