In recent years, light and thin-sized machines/instruments progress remarkably. Therefore, parts, e.g., mechanical springs used in those machines/instruments are more small/ thin-sized and flexible. In application of flexible parts, it is very important to check stress and deformation of materials used in those parts. And uniformity of their mechanical properties has to be guaranteed more and more. The establishment of a method of useful property evaluation test is required thereof. The research committee on evaluation of elastic property for thin plates and wires focused its activity on Young's modulus among various mechanical properties and developed a new and unique measuring method (Axial Compression Method) to evaluate Young's modulus of flexible materials by analyzing the buckling of an elastic column at large deformations. In the committee, various tests were performed to confirm the applicability of the new evaluating method by using four kinds of flexible piano wires (SWP-B) and data were accumulated. As a result, it is made clear that the new method is suitable for flexible wires. The new method proposed in this report can be applied suitably to other highly flexible materials (thin plates/sheets, composites, glass fibers, carbon fibers, optical fibers, etc.).
