The growth of sapphire single crystals
(Serbian Chemical Society, 2001)
Sapphire (Al2O3) single crystals were grown by the Czochralski technique both in air and argon atmospheres. The conditions for growing sapphire single crystals were calculated by using a combination of Reynolds and Grashof ...
Numerical modeling of ductile fracture initiation in structural steel / Numeričko modelisanje inicijalizacije daktilne frakture u strukturnom čeliku
(University of Niš, 2001)
Numerical modeling of ductile fracture initiation on a precracked geometry, taking into account the behaviour of simple uncracked material, has been done in the scope of micromechanical analysis. Numerical simulation has ...
Analysis of crack initiation by micromechanism of ductile fracture in structural steel / Analiza nastanka prsline mikromehanizmom žilavog loma u konstrukcionom čeliku
(Vojnotehnički institut, Beograd, 2001)
In the presented paper a micromechanical model based on a particular flow criterion of a porous solid has been applied. In this study crack initiation in the smooth specimen made of steel 22 NiMoCr 3 7 has been analyzed; ...
Delamination detection in woven composite laminates with embedded optical fibers
(Wiley-VCH Verlag Gmbh, Weinheim, 2001)
Methanol oxidation on an ink type electrode using Pt supported on high area carbons
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
Methanol oxidation was investigated on the following Pt catalysts: bare Pt electrode, Pt covered by nafion (R) film, and pt catalysts supported on high area carbons in the form of an ink. The reaction was carried out using ...
Radioactive reliability of programmable memories
(Japanese Journal of Applied Physics Part 1-Regular Papers Short Notes and Review Papers, 2001)
In this study, we examine the reliability of erasable programmable read only memory (EPROM) and electrically erasable programmable read only memory (EEPROM) components under the influence of gamma radiation. This problem ...
RF Plasma Treatment of Wool
(Nagoya University, 2001)
Recycled Wool Based Non-Woven Material as Sorbent for Heavy Metals
(University of Minho, Portugal, 2001)
The aim of this study was to investigate the sorption properties of recycled wool based non-woven material for heavy metal ions. To improve sorption properties wool material was treated with air low-temperature plasma (LTP) ...
Some observations on the shear fracture mode in AlMg6.5 alloy sheet
(Frankfurt : Werkstoff-Informationsgesellschaft mbH, 2001)
AlMg6.5 alloy sheet samples with different width to thickness ratio (w/t=2.5-8.3) were tested in uniaxial tension test. SEM observations revealed transgranular ductile dimple type of failure occured by shear process. It ...
Influence of the woven construction on breaking load and relaxation / Uticaj Konstrukcije Tkanine na Prekidnu Silu i Relaksaciju
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2001)
A study is made to establish the correlation between a woven construction and its mechanical strength. Dynamometric tests are carried out to determine the breaking load and breaking extension of three wooltype fabrics, as ...
