A novel method to determine Poisson's ratio by beta-ray absorption experiment

In this paper a new experimental method is applied to determine Poisson's ratio of an industrial rubber tape based on the attenuation of beta particles. A simple theoretical model is presented and the experimental results are compared with the model's prediction. Poisson's ratio of the rubber is obtained by applying a steady state strain force. The relatively good agreement between the model's prediction and the experimental results could be a verification test for the presented method. - Highlights: ► This paper indicates a novel method to determine Poisson's ratio by beta absorption. ► A simple model is presented and the experimental results are compared with its prediction. ► The method utilizes typical values in defining properties such as Young's modulus. ► Good agreement is obtained between the model's prediction and the experimental results.
