Caracterización dinámica de distintos tipos de sandwich con núcleos de Honeycomb por medio de la prueba Split-Hopkinson
(Universidad de los AndesIngeniería MecánicaFacultad de IngenieríaDepartamento de Ingeniería Mecánica, 2018)
El análisis del comportamiento dinámico de las estructuras celulares con núcleos en honeycomb resulta esencial hoy en día debido la versatilidad de este material para el aporte de nuevas aplicaciones en la industria ...
The mechanics of additively manufactured reentrant honeycombs: apparent elastic modulus and energy absorption ability under cyclic loadings.
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2021-06-14)
Advances in additive manufacturing (AM) technologies have made possible the design and fabrication of more complex parts such as the cellular solids. Auxetic honeycombs are a type of cellular solid with already demonstrated ...
A mathematical basis for the graphene
(2020)
We present a new basis of representation for the graphene honeycomb structure that facilitates the solution of the eigenvalue problem by reducing it to one dimension. We define spaces in these geometrical basis that allow ...
On the graphene Hamiltonian operator
(2020)
We solve a second-order elliptic equation with quasi-periodic boundary conditions defined on a honeycomb lattice that represents the arrangement of carbon atoms in graphene. Our results generalize those found by Kuchment ...
Quantum phases in the frustrated Heisenberg model on the bilayer honeycomb lattice
(American Physical Society, 2014-01)
We use a combination of analytical and numerical techniques to study the phase diagram of the frustrated Heisenberg model on the bilayer honeycomb lattice. Using the Schwinger-boson description of the spin operators followed ...
Exotic disordered phases in the quantum J1-J2 model on the honeycomb lattice
(American Physical Society, 2013-01)
We study the ground-state phase diagram of the frustrated quantum J 1-J2 Heisenberg antiferromagnet on the honeycomb lattice using a mean-field approach in terms of the Schwinger boson representation of the spin operators. ...
Jamming and percolation of linear k -mers on honeycomb lattices
(American Physical Society, 2020-09)
Numerical simulations and finite-size scaling analysis have been performed to study the jamming and percolation behavior of elongated objects deposited on two-dimensional honeycomb lattices. The depositing particle is ...
The effect of different slurry compositions and solvents upon the properties of ZSM5-washcoated cordierite honeycombs for the SCR of NO x with methane
(Elsevier Science, 2005-10)
ZSM5-washcoated monoliths were prepared using different slurry compositions and the following solvents: water, methyl alcohol, ethyl alcohol, isopropyl alcohol, butyl alcohol, ethyl acetate, and acetone. The effect of the ...
Broken discrete symmetries in a frustrated honeycomb antiferromagnet
(American Physical Society, 2013-03)
We study the magnetic phase diagram of the J1-J2 Heisenberg antiferromagnet on a honeycomb lattice at the strongly frustrated point J2/J1=1/2 using large-scale Monte Carlo simulations. At low temperatures we find three ...
Diseño, fabricación y caracterización mecánica de estructuras "honeycomb" tras la reducción de su peso a través de distintas configuraciones de agujero
(Universidad de los AndesIngeniería MecánicaFacultad de IngenieríaDepartamento de Ingeniería Mecánica, 2018)
El presente Proyecto de Grado pretende comprender el comportamiento de los Honeycomb tras la disminución de su peso. Con ello, se busca determinar si la implementación de un diseño atípico que incorpore agujeros en las ...
