Abstract Reflection characteristics of longitudinal strain waves in a semi-infinite elastic rod connected to a viscoelastic stratum are investigated analytically. The three-dimensional viscoelastlcity theory is applied to the stratum, and the Laplace transform with respect to time and the numerical inverse Laplace transform by means of Laguerre function are used. The time histories for the longitudinal strain of an arbitrary point of the rod are presented. Two typical viscoelastic models are considered, one is the usual Maxwell-Voigt model, the other is whose relaxation function is given by a power law. The numerical results for the two models are presented and compared each other and also with previously published results for the elastic stratum.
