Optimization of the mechanical properties of low-carbon steels by formation of a multiphase microstructure
(2001-12-01)
In this work five methods of heat treatments are investigated in order to obtained convenient volume fractions of ferrite, bainite, martensite and retained austenite, starting with a low carbon steel and seeking the ...
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 ...
Estimation of electrical machine speed using sensorless technology and neural networks
(2008-12-01)
The use of sensorless technologies is an increasing tendency on industrial drivers for electrical machines. The estimation of electrical and mechanical parameters involved with the electrical machine control is used very ...
Diffusion phenomena of the oxygen and nitrogen in niobium by mechanical spectroscopy
(2010-05-19)
The short-range diffusion phenomenon (Snoek Effect) was investigated by mechanical spectroscopy measurements between 300 K and 650 K, in a polycrystalline niobium sample, containing oxygen and nitrogen, using a torsion ...
Experimental Estimation Of Mechanical Joint Parameters Using Frequency Response Functions And Modal Parameters
(Publ by Society of Photo-Optical Instrumentation Engineers, Bellingham, WA, United States, 1993)
Experimental validation of relationship between fracture parameters j and ctod for se(b) and se(t) specimens during ductile crack growth
(SOBENARio de Janeiro, 2014-11-10)
In structural assessments analysis the crack driving force is usually estimated numerically based on the J-integral definition because its determination is well establidhed in many finite element codes...
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 ...
An investigation of electrolytic surface damages and electroplated crhomium effects on fatigue behavior of high strength steel
(2001-12-01)
Fatigue crack initiation occurs at the surface, although sub surface nucleation has also been reported. Localized imperfections like inclusions close to surface and surface small pits can result in crack sources. Coatings ...
Optimization of the parameters of a PID controller
(ABCMRibeirao Preto, 2013-11-03)
The methodology proposed is applied and it is presented the results for two case studies, one for the dynamic positioning of a vessel modeled with one degree of freedom (longitudinal movement) and another with three degrees ...
