On the wave propagation in micro-inhomogeneous media

The wave propagation problem in periodic fibre-reinforced linear-elastic materials is investigated. The approach is based on the equations of refined macrodynamics proposed by Woźniak (1993) and generalizes the results obtained previously by Mielczarek and Woźniak (1995). Its main feature is a possibility of obtaining resulting formulas for the spectral lines and the phase velocities in a simple analytical form.
