Abstract
Provided is an evaluation method capable of evaluating stress on a bond which is difficult to detect by Raman spectroscopy. The present disclosure relates to an evaluation method including using infrared absorption spectra measured on a rubber specimen under application of no tensile force and under application of a tensile force to calculate an amount of peak shift caused by application of the tensile force, and evaluating stress in the rubber specimen from the amount of peak shift.
