INDENTATION TEST METHOD AND INDENTATION TEST DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an indentation test method and an indentation test device capable of correctly estimating a deformation behavior, that is, a mechanical property of a bilinear flexible body.;SOLUTION: An indentation test method includes a step of calculating a young's modulus, a plateau stress, and a softening rate of a sample SP1 using an indentation amount of an indenter 15 when the indenter 15 is pushed into the sample SP1 and an indentation load acting on the indenter 15. The step of calculating the young's modulus, the plateau stress, and the softening rate of the sample SP1 uses the indentation amount with a reference indentation amount representing the indentation amount when the indenter 15 comes into contact with the sample SP1 for the first time when the indenter 15 is made to approach the sample SP1 from a state in which the sample SP1 and the indenter 15 are not in contact with each other.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
