In this paper, a finite element method based on the ABAQUS code and user subroutines is presented to evaluate the propagation of elastic waves in a phononic crystal slab with Archimedean-like tilings. Three systems composed of cylinders embedded in host materials in square, ladybug and bathroom lattices are considered. Complete and accurate band structures and transmission spectra are obtained to...
In this paper, a computational method based on finite element method is presented to evaluate the propagation of acoustic waves through three-dimensional phononic crystals consisting of simple cubic (SC), body-centered cubic (BCC) or face-centered cubic (FCC) array spheres embedded in a host. Complete and accurate band structure information is obtained to identify the band gaps and eigenmodes. The...
