OS0206 A New Young's Modulus Measuring Method Based on Large Deflections Due to Own Weight in Flexible Materials

Abstract

In this study, a new and convenient mechanical testing method is provided for measuring the Young's modulus in a flexible material. The method is based on a nonlinear deformation theory that takes into account large deformation behaviors of the flexible material. By means of measuring the horizontal displacement or the vertical displacement, the Young's modulus can be easily obtained for various thin and long flexible materials. Measurements were carried out on a Piano wire (SWPA). The results confirm that the new method is suitable for flexible materials.
