Description

Wave propagation in composite materials with discrete changes in properties has been extensively studied and is well understood. In contrast, wave propagation in composites with smooth continuous periodic stiffness variations has only begun to be studied [1]. Use of direct analysis techniques for wave propagation in a composite material with varying stiffness has lead to mathematical contradictions and has indicated the need for a different approach [2]. The present study investigated wave propagation in a composite with smooth continuous periodic stiffness variations using perturbation techniques and a model simulation with a refined finite difference method.

Perturbation and Finite Difference Solutions for Wave Propagation in Composites with Periodic Stiffness Variations
