Paper Abstract

A method for homogenization of an elastic composite with periodic microstructure is presented, focusing on the Floquet-type elastic waves. The resulting homogenized frequency-dependent elasticity and mass-density then automatically satisfy the overall conservation laws and by necessity produce the exact dispersion relations. The method is used to calculate the dynamic effective parameters for a layered composite by using the exact solution.
