2013 Examination of measuring method for mechanical characteristics of SUS304 thin sheet by micro indentation method
Details
Nanoindentation is used for evaluating the mechanical properties of thin films and microstructures. However, it is not examined whether nanoindentation can apply to thin sheet. Therefore, the establishment of the test method for the thin sheet is necessary. In this study, SUS304 thin sheets with thicknesses of 20, 50, 100 and 1000μm were used. Specimens were glued to metal block with thickness of 5mm using 2 kind of adhesive, Young's modulus was measured. As the results, Young's modulus was almost constant in the low indentation load region, but decreased when indentation load is more than a certain value. Young's modulus by indentation method agreed almost with that by tensile test.
