Strongly Nonlinear Transverse Perturbations in Phononic Crystals [PDF]
, 2014 The dynamics of the surface heterogeneities formation in low-dimensional phononic crystals is studied. It is shown that phononic transverse perturbations in this medium are highly nonlinear. They can be described with the help of the Riemann wave and may

Asymptotic Modeling of Phononic Box Crystals
SIAM Journal on Applied Mathematics, 2019 We introduce phononic box crystals, namely, arrays of adjoined perforated boxes, as a three-dimensional prototype for an unusual class of subwavelength metamaterials based on directly coupling resonating elements. In this case, when the holes coupling the boxes are small, we create networks of Helmholtz resonators with nearest-neighbor interactions. We

Vibration attenuation in two-link flexible mechanical arms with periodic composite materials
Advances in Mechanical Engineering, 2015 We introduce the periodic composite materials, so-called phononic crystals, to the flexible mechanical arms systems. Due to the transfer matrix method and the Bloch theorem, the theoretical solution of band structure of the two-link model is deduced and ...
