摘要
A measurement apparatus for carrying out an indentation creep test on a specimen, including a measurement control apparatus that includes a load measurement device, a constant-load compression device configured to compress a tip of a transparent indenter to a surface of the specimen, and an image capturing device configured to optically capture an image including a contact area portion which is a part of the specimen to which the load is applied by the constant-load compression device. The apparatus also includes an information processing apparatus that includes an image analysis unit configured to analyze a contact area, and a physical property value calculation unit. The physical property value calculation unit conducts linear regression with respect to a plot of a logarithmic value of the contact stress and a logarithmic value of the contact strain rate so as to determine a creep index n and creep constant k.
