摘要
PROBLEM TO BE SOLVED: To measure thermal influence by plastic deformation in a sample to which cyclic loads are applied, by using an infrared sensor with sufficient accuracy.;SOLUTION: A tensile load and a compressive load are repeatedly and alternately applied to the sample 16 by a constant repetition frequency with a vibration generator 10, and a change in temperature of the sample 16 on this occasion is detected with an infrared camera 18. This detected temperature signal outputted by the infrared camera 18 is multiplied by a waveform signal having a frequency 2n (n is a natural number) times the repetition frequency. Time integral of a signal generated in this way is performed to compute a value to be an index representing a degree of thermal influence of the plastic deformation in the sample 16, and its image display is performed.;COPYRIGHT: (C)2006,JPO&NCIPI
