The indentation tests for three materials (aluminum alloy, phosphor bronze, stainless steel) are carried out,obtained loading and unloading curve, respectively. From unloading curve, exponential index and finish point of each curve are derived. As a result, it turns out that the exponential index of unloading curve was 1.5, although with different materials. Consequently, calculated Young\u0027s moduli using exponential index are approximately consistent with measured Young\u0027s modulus.", "subitem_description_type": "Abstract"}]}, "item_8_full_name_3":
