Pinning of elastic ferromagnetic/antiferromagnetic interfaces in phase-separated manganites
(IOP Publishing, 2012-10)
We present a study of the magnetic properties of the Pr 0.5Sr 0.5xCa xMnO 3 manganite (x=0.1 and 0.2) in the temperature region where phase separation occurs. This state is characterized by the presence of ferromagnetic ...
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 ...
Freezing resistance in Patagonian woody shrubs: the role of cell wall elasticity and stem vessel size
(Oxford University Press, 2016-03)
Freezing resistance through avoidance or tolerance of extracellular ice nucleation is important for plant survival in habitats with frequent subzero temperatures. However, the role of cell walls in leaf freezing resistance ...
Brazilian Import Demand of Dairy Products with Emphasis in the Mercosul ContextDemanda brasileira de importações de laticínios com ênfase no contexo do mercosul
(Universidade Federal de Minas Gerais. Departamento de Ciências Econômicas, 2020-05)
Brazil is the largest milk producer in South America, with an increasing trend in the last 20 years which allowed the country to start exporting some output. However, it has not become self-reliant and continues to be a ...
Calculation of cancellous bone elastic properties with the polarization-based FFT iterative scheme
(Wiley Blackwell Publishing, Inc, 2017-11-03)
The Fast Fourier Transform–based method, originally introduced by Moulinec and Suquet in 1994 has gained popularity for computing homogenized properties of composites. In this work, the method is used for the computational ...
Contribution of Entanglements to Polymer Network Elasticity
(American Chemical Society, 2017-04-23)
Trapped entanglements, cross-linker functionality, and elastically effective chains are the sources of elasticity of polymer networks and gels. However, despite more than 80 years of theoretical and experimental research ...
Topology design of 2D and 3D elastic material microarchitectures with crystal symmetries displaying isotropic properties close to their theoretical limits
(Elsevier, 2019-11)
This paper evaluates the effect that different imposed crystal symmetries have on the topology design of two-phase isotropic elastic composites ruled by the target of attaining extreme theoretical properties. Extreme ...
Hardness and elastic modulus profiles of hybrid coatings
(Springer, 2005-04)
Instrumented-indentation testing (IIT) provided with a continuous stiffness measurement (CSM) technique was employed to measure hardness and elastic modulus profiles of thin organic/inorganic hybrid coatings on glass ...
Influence of quenched-in vacancies on the elastic modulus and its dependence on the temperature in β CuAlBe shape memory alloys
(Elsevier, 2019-08)
The influence of quenched-in vacancies on the elastic modulus and its dependence on the temperature was studied in a β CuAlBe polycrystalline shape memory alloy. Samples with different quenching temperatures were submitted ...
Statistics of zero crossings in rough interfaces with fractional elasticity
(American Physical Society, 2018-04-24)
We study numerically the distribution of zero crossings in one-dimensional elastic interfaces described by an overdamped Langevin dynamics with periodic boundary conditions. We model the elastic forces with a Riesz-Feller ...
