INDENTING TYPE MATERIAL TESTING MACHINE, TESTING METHOD, AND TESTING PROGRAM PRODUCT

摘要

An indenter is pressed against a sample, displacement of the indenter is detected, and a testing force applied to the sample by the indenter is detected. FFT analysis is performed on the displacement detection signal of the indenter detected under a no-load state in order to detect the frequency band of noise. Filter characteristics are calculated based on the frequency band thus detected and the displacement detection signal is filtered according to the filter characteristics. Physical properties of the sample are evaluated based on the filtered displacement detection signal and the testing force.
