Abstract
The objective of the paper is to investigate the propagation behavior of horizontally polarized shear waves (SH-waves) in an inhomogeneous fiber-reinforced layer which is sandwiched between two microstructural half-spaces. The half-spaces are modeled using size-dependent consistent couple stress theory. The mathematical formulations of consistent couple stress theory contains a length scale parameter called characteristic length. Characteristic length is comparable with the size of internal microstructure of the material and introduces the role of size dependency into the problem. The propagation behavior of SH-waves is investigated in an inhomogeneous fiber-reinforced layer under two different scenarios, first when the layer is perfectly attached to the half-spaces and second when the layer is in imperfect contact with the half-spaces. Dispersion and damping relations are calculated for the propagation of SH-waves in both cases separately using suitable boundary conditions. Some special cases are also generated under different conditions. The impact of various parameters such as characteristic length, inhomogeneity, reinforcement, and imperfectness are manifested graphically on the phase and damping velocities of the SH-waves.
