A finite element formulation for stressed bodies with continuous distribution of edge dislocations
(Springer Wien, 2015)
On using Noll's theory of materially uniform but inhomogeneous bodies, a nonlinear finite element method for treating a body with a continuous distribution of edge dislocations is presented. To this end, we use the ...
Entanglement and control operations in Heisenberg 3-D interactions of two qubits
(Revista Mexicana de Física, 2010)
Effect of stirring on photoinitiated polymerization
The polymerization of methyl methacrylate photosensitized by benzion methyl ether over a wide range of initiator absorbances was investigated. Both the polymerization rate and the polymer molecular weight distribution are ...
A solid-like FEM for geometrically non-linear 3D frames
(ELSEVIER SCIENCE SA, 2009)
This study presents a solid-like finite element formulation to solve geometric non-linear three-dimensional inhomogeneous frames. To achieve the desired representation, unconstrained vectors are used instead of the classic ...
Torsional wave propagation in a pre-stressed hyperelastic annular circular cylinder
(Oxford Univ PressOxfordInglaterra, 2013)
Collimated scanning LS-INAA for testing trace elements homogeneity in Brazilian coffee beans
The degree of homogeneity is normally assessed by the variability of the results of independent analyses of several (e.g., 15) normal-scale replicates. Large sample instrumental neutron activation analysis (LS-INAA) with ...
Simple and cost-effective method to obtain RE3+-doped Al2O3 for possible photonic applications
Materials containing rare earth ions with photoluminescent properties have been investigated as efficient phosphors for applications in photonics. In this work We reports on preparation of Eu3+-doped Al2O3 with different ...
Segregação do índio em cristais Ga1-xInxSb obtidos pelo método bridgman vertical
(Pontifícia Universidade Católica do Rio Grande do SulPorto Alegre, 2012)
Este trabalho descreve o crescimento e a caracterização de cristais de compostos semicondutores III-V, Ga1-xInxSb levemente dopados com Alumínio (Al) e cádmio (Cd). O composto Ga1-xInxSb é um material interessante para o ...
