<P>PROBLEM TO BE SOLVED: To provide a stress history recording system in which stress luminescence induced by the stress equal to or greater than a specified value can be selectively recorded, when luminescence obtained from a stress illuminant is integrated and recorded for a certain period of time. <P>SOLUTION: A stress history recording medium 10 comprises: a light-emitting part 1 containing stress-induced luminescent material that emits light in response to mechanical stress; and a recording part 2 for recording a history of photoreaction generated by luminescence from the light-emitting part 1. Further, an optical intensity of stress luminescence in the light-emitting part 1 is matched with a photosensitive threshold level at which reciprocity law failure is indicated by the recording part, by using stress luminescence adjustment processing conducted before a first step of affixing the stress history recording medium 10 on a measurement object. <P>COPYRIGHT: (C)2013,JPO&INPIT |
