Abstract
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.
