Diffusion of Interstitial Solutes in Nb-46wt% Ti Alloys Measured by Mechanical Spectroscopy
(Trans Tech Publications Ltd, 2012-01-01)
The mechanical properties of metals with a body-centered cubic (bcc) structure, such as Nb, Ta, V, and their alloys, are modified with the introduction of interstitial impurities, such as O, N, C, or H. These metals can ...
Variational Formulation for Quaternionic Quantum Mechanics
(Birkhauser Verlag Ag, 2010-10-01)
A quaternionic version of Quantum Mechanics is constructed using the Schwinger's formulation based on measurements and a Variational Principle. Commutation relations and evolution equations are provided, and the results ...
ANALYSIS OF EFFICIENCY IN LIQUID SEAL WITH THE USE OF MECHANICAL SEAL
(Inegi-inst Engenharia Mecanica E Gestao Industrial, 2016-01-01)
Sealing systems plays an important role in the industry, the study of the components of these systems evaluates and predicts the life of equipment working under harsh regimes. This paper proposes the development of a bench ...
Neural Network Prediction of the Trabecular Bone Mechanical Competence Parameter
(Springer, 2014-01-01)
The mechanical competence parameter (MCP) has been defined to grade the trabecular bone fragility based on the principal component analysis (PCA) evaluated in terms of volume fraction, connectivity, tortuosity and Young ...
Vibrations due to impact in a non ideal mechanical system with a non-linear Hertzian contact model
(2014-01-01)
This work analyses the post impact behavior of a mechanical system consisting of an oscillator and an unbalanced non-ideal electrical motor. The impact between the mechanical system and a rigid wall is based on the assumption ...
Mechanical properties of HIPS/sugarcane bagasse fiber composites after accelerated weathering
(Elsevier B.V., 2011-01-01)
The effect of accelerated weathering on the visual appearance and on mechanical properties of high impact polystyrene (HIPS) as well as HIPS reinforced with mercerized and bleached sugarcane bagasse fibers composites are ...
Diffusion of Interstitial Elements in Ti Alloys used as Biomaterials
(Trans Tech Publications Ltd, 2009-01-01)
Titanium alloys are excellent implant materials for orthopedic applications due to their desirable properties, such as good corrosion resistance, low elasticity modulus, and excellent biocompatibility. The presence of ...
Diffusion of Oxygen and Nitrogen in the Ti-15Mo Alloy used for Biomedical Applications
(Trans Tech Publications Ltd, 2012-01-01)
The Ti-15Mo alloy is a promising material for use as a biomaterial because of its excellent corrosion resistance and its good combination of mechanical properties, such as fatigue, hardness, and wears resistance. This alloy ...
Mechanical behavior of carbon fiber/epoxy filament wound laminates exposed to hygrothermal conditioning
(2015-01-01)
This work aims to evaluate the effect of hygrothermal conditioning on the tensile, in-plane shear and viscoelastic properties of carbon fiber/epoxy laminates (fiber volume fraction ≈ 70%). The flat unidirectional laminates ...
Electrical behavior of PU/POMA blends
(2005-12-01)
The incorporation of conducting polymer into a conventional polymer matrix has received attention because of the possibility of combining the good processability and mechanical performance of the conventional polymer with ...
