| Abstract: | Abstract The dispersive and damping characteristics of longitudinal and flexural waves in a long PVC beam are studied experimentally.The complex compliance is obtained from longitudinal impact test using the Fourier analysis.The reliability of the results and some prob- lems involved in estimating the shear complex modulus by flexural impact test are discussed. |
