In application of flexible thin materials, it is very important to evaluate mechanical properties of these materials in both analytical and technological interests. In this study, a new and convenient mechanical testing method (Own-Weight Cantilever Method) is provided for measuring Young's modulus in flexible materials (thin plate, or wire). The method is based on a nonlinear theory that takes into account the large deformation behavior of flexible materials. By means of measuring horizontal or vertical displacement at the free end of a cantilever, Young's modulus can be easily obtained for various thin plate or wire materials. In this study, measurements were carried out on a thin piano wire. The result reveals that the new method is suitable for thin flexible materials. In the meantime, the new "Own-Weight Cantilever Method" proposed in this paper is quite a promising method and can be extended to measure Young's modulus of every thin layer in a flexible multilayered material formed by PVD, CVD, Electrodeposition, Coating, Paint, Cladding, Lamination, and others.
