Title:
INDENTATION TESTING DEVICE AND INDENTATION TESTING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/195798
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a compact and light-weight indentation testing method and indentation testing device for accurately measuring the softness of an object. [Solution] Provided is an indentation testing device for pressing an indenter into a sample, wherein the indentation testing device comprises: an enclosure having a pressing surface to be pressed against the sample; the indenter, which is arranged so as to protrude out by a predetermined amount from the pressing surface, and is indented into the sample; a load cell that is arranged between the enclosure and the indenter and that measures at least a force parallel to an indenting direction and acting on the indenter; and a Young's modulus display unit for calculating and displaying the Young's modulus of the sample on the basis of the force acting on the indenter when the pressing surface and the sample have made contact, as measured with the load cell.
