N2 - In this work, we consider elastic wave prorogation in deformable microstructured materials. In particular, we focus on the influence of externally applied deformation on the acoustic characteristic of periodic layered phononic crystals. Based on an analytical solution for the finitely deformed layered media, an analysis of the superimposed on the finitely deformed state small amplitude motions is performed. The analysis provides the information about the important acoustic characteristics such as phase and group velocities, illustrated by the slowness and energy curves. The influence of deformation on these characteristics of phononic crystals is investigated, showing the strong tunability of the phononic crystals by applied deformations.
