Longitudinal impact tests on a rectangular diallyl phthalate (DAP) polymer strip were performed to make clear the attenuation properties of compressive strain waves. The attenuation of the peak value of the strain pulse with travelling distance was investigated in conjunction with the duration of the pulse. Material properties, or constitutive equation necessary for the analysis of the impact response were determined by the complex compliances obtained from the Fourier components of strain waves. A method, or the offset method for correcting strain pulse profiles was newly developed. This method eliminates the influence of noise in strain signals on the amplitude spectra, and contributes to the improvement of the accuracy of determining the complex compliances. The attenuation of the peak value of the strain pulse with travelling distance was theoretically predicted. The discrepancy between the theoretical predictions and the experimental values was within 6%.
