摘要：

This paper investigates effects of inertial amplification mechanisms on the phononic band structure of infinitely periodic simple cubic (SC) and body centered cubic (BCC) lattices. First, these three-dimensional lattices are formed using mass and spring elements. Then, dispersion curves of these lattices are obtained. Consequently, inertial amplification mechanisms are embedded around each spring in these lattices and their dispersion curves are calculated again. When compared to the cases in which inertial amplification was not used, phononic band gaps are obtained at much lower frequencies.
