Abstract

The macroscopic wave equation describing the propagation of nonlinear strain waves in a fibre- reinforced composite material with an imperfect bonding between the components is obtained. For this aim, the higher-order asymptotic homogenization method is developed. Effective elastic coefficients are evaluated and the analysis of the obtained numerical results is presented.
