| Abstract: | Propagation of strain waves is experimentally investigated under impact loading of a rod system composed of steel cylinders separated by pliable interlayers. The existence of pendulum-type waves is confirmed. In order that wave process in the rod system is numerically described, a viscoelastic model of deforming materials of interlayers used in the experiment is constructed. It is shown that the velocity of waves and the degree of their attenuation are to a great extent dependent on viscous properties of the material of interlyers.__________Translated from Fiziko-Tekhnicheskie Problemy Razrabotki Poleznykh Iskopaemykh, No. 6, pp. 49–57, November–December, 2004. |
