Propagation of waves in a cylindrical bore filled with viscous liquid embedded in a microstretch elastic medium is investigated. Frequency equation for the surface wave propagation near the surface of the cylindrical bore is obtained, characterizing the dispersive nature of the wave. Significant effects of viscosity, microstretch and micropolarity are observed. Some special cases have been deduced. (C) 2002 Elsevier Science Ltd. [References: 20]
