FE-simulations with a simplified model for open-cell porous materials: A Kelvin cell approach
(IOS Press, 2019-01-01)
In in-silico estimation of mechanical properties of open (Kelvin) cell porous materials, the geometrical model is intractable due to the large number of finite elements generated. Such a limitation impedes the study of ...
A microarchitecture design methodology to achieve extreme isotropic elastic properties of composites based on crystal symmetries
(Springer, 2021-02-07)
The present contribution describes an optimization-based design technique of elastic isotropic periodic microarchitectures with crystal symmetries aiming at the realization of composites with extreme properties. To achieve ...
Predicting the vibrational contribution to thermal and EOS properties of Ni3X (X=In,Sn) intermetallic compounds
(Pergamon-Elsevier Science Ltd, 2020-09)
Two computational approaches to the vibrational part of thermal properties and equation-of-state parameters of the Ni3Sn(hP8), Ni3Sn(cP4), Ni3In(hP8) and Ni3In(cP4) intermetallic phases, of interest in the study of lead-free ...
Ab-initio study of elastic anisotropy, hardness and volumetric thermal expansion coefficient of ZnO, ZnS, ZnSe in wurtzite and zinc blende phases
(Pergamon-Elsevier Science Ltd, 2019-11)
Structural, thermoelastic, and mechanical properties of ZnO, ZnS, ZnSe in wurtzite and zinc blende phase have been studied using SIESTA code. The elastic anisotropies in the single crystal were analysed by means of the ...
Evaluación de propiedades elásticas de la fundición nodular empleando micromecánica computacionalDerivation of nodular cast iron elastic properties via computational micromechanics
(Univ Politecnica Catalunya, 2015-04)
Nodular cast iron is a Fe-C-Si metallic alloy whose microstructure consists of a matrix, composed in general of ferrite and pearlite, with graphite nodules embedded in it. Owing to its microscopical heterogeneity, the ...
Large-scale societal factors and noncommunicable diseases: Urbanization, poverty and mortality spatial patterns in Argentina
(Elsevier Ltd, 2017-09)
In developing countries, the rapid increase in noncommunicable diseases burden has been accompanied by socio-demographic changes, such as rapid urbanization, with persistence of considerable socio-economic gaps between ...
Ab Initio Study of the Electronic Structure, Elastic Properties, Magnetic Feature and Thermodynamic Properties of the Ba2NiMoO6 Material
(Springer/Plenum Publishers, 2018-05)
We report first-principles calculations of the elastic properties, electronic structure and magnetic behavior performed over the Ba2NiMoO6 double perovskite. Calculations are carried out through the full-potential linear ...
Optomechanical properties of GaAs/AlAs micropillar resonators operating in the 18 GHz range
(Optical Society of America, 2017-10-02)
Recent experiments demonstrated that GaAs/AlAs based micropillar cavities are promising systems for quantum optomechanics, allowing the simultaneous three-dimensional confinement of near-infrared photons and acoustic phonons ...
A Free Vibration Analysis of Microbeams by Modified Strain Gradient Theory
(Nova Science Publishers, 2018)
The paper presents a model based on the modified strain gradient theory for the free vibration analysis of isotropic microbeams. The analysis includes the effects of rotatory inertia and shear deformation on natural ...
