Comparing Young's Modulus Values of Paperboard Obtained by Four Methods

Abstract

Young's modulus of paperboard was obtained from tensile, static bending, longitudinal vibration, and flexural vibration tests under various specimen configurations, and the obtained values were compared with each other. There were significant differences among the Young's modulus values obtained by the four methods because the lamination construction and inelastic deformation of the paperboard affected the measurement of Young's modulus. Therefore, the method for measuring the Young's modulus should be carefully determined while considering the practical application of using the paperboard.
