Analysis of the directionality on periodic materials
Nicolás Guarín-Zapata, Camilo Valencia, Juan Gómez
There is an increasing interest in the study of metamaterials and periodic materials across disciplines. These are anisotropic and their properties present directionality. For exam…
Computational characterization of the wave propagation behaviour of multi-stable periodic cellular materials
Camilo Valencia, David Restrepo, Nilesh D. mankame +2
In this work, we present a computational analysis of the planar wave propagation behavior of a one-dimensional periodic multi-stable cellular material. Wave propagation in these ma…
Finite element modeling of micropolar-based phononic crystals
Nicolás Guarín-Zapata, Juan Gomez, Camilo Valencia +2
The performance of a Cosserat/micropolar solid as a numerical vehicle to represent dispersive media is explored. The study is conducted using the finite element method with emphasi…
A general-purpose element-based approach to compute dispersion relations in periodic materials with existing finite element codes
Camilo Valencia, Juan Gomez, Nicolás Guarín-Zapata
In most of standard Finite Element (FE) codes it is not easy to calculate dispersion relations from periodic materials. Here we propose a new strategy to calculate such dispersion…
