SINOPSIS

Axial-shear vibrations of an infinitely long poroelastic composite circular cylinder are investigated employing Biot's theory of wave propagation in poroelastic media. A composite poroelastic cylinder consists of two concentric poroelastic layers, both of which are infinitely long, made of different poroelastic materials. Let the poroelastic composite cylinder be homogeneous, isotropic, and the boundaries free from stress. The frequency equations of axial-shear vibrations for poroelastic composite circular cylinders, poroelastic composite bores, poroelastic composite cylinders with rigid casing, and poroelastic composite solid cylinders with rigid casing are derived as particular cases. The nondimensional frequency for propagating modes is computed as a function of the ratio of the inner radius of the core to the interface radius. The displacement of poroelastic composite cylinders is determined. The results are presented graphically for two types of poroelastic composite cylinders and then discussed. Previous works are obtained as some particular cases of present study.
