Poisson's Ratio Measurement Using a Pair of PVDF Ultrasonic Transducer
Vargas, Enrique,Toral, Sergio,Gonzalez, Vicente The Korean Society for Nondestructive Testing 2009 한국비파괴검사학회지 Vol.29 No.6
This work presents a simple technique to determine the Poisson's ratio of homogeneous solid material using a pair of low cost PVDF ultrasonic transducers. It is based on transducer's property of generating longitudinal and transversal waves depending on the excitation frequency. Mechanical tests were conducted to validate the proposed method, resulting in a good agreement between ultrasonic and mechanical techniques.
