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…
A Sinusoidally-Architected Helicoidal Biocomposite
Nicholas A. Yaraghi, Nicolás Guarín-Zapata, Lessa K. Grunenfelder +11
A fibrous herringbone-modified helicoidal architecture is identified within the exocuticle of an impact-resistant crustacean appendage. This previously unreported composite microst…
Shear Wave Filtering in Naturally-Occurring Bouligand Structures
Nicolás Guarín-Zapata, Juan Gomez, Nick Yaraghi +2
Wave propagation was investigated in the Bouligand-like structure from within the dactyl club of the Stomatopod, a crustacean that is known to smash their heavily shelled preys wit…
Evaluation of the Spectral Finite Element Method With the Theory of Phononic Crystals
Nicolás Guarín-Zapata, Juan Gomez
We evaluated the performance of the classical and spectral finite element method in the simulation of elastodynamic problems. We used as a quality measure their ability to capture…
Seismic Wave Scattering Through a Compressed Hybrid BEM/FEM Method
Nicolás Guarín-Zapata, Juan Gómez, Juan Jaramillo
Approximated numerical techniques, for the solution of the elastic wave scattering problem over semi-infinite domains are reviewed. The approximations involve the representation of…
