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; ...
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 ...
Ion/surface collisions: An alternative to gas-phase collisional activation in mass spectrometry
(Serbian Chemical Society, 2001)
Collisions of ions at solid surfaces result in a number of phenomena, of which surface-induced dissociation (SID) is the most important. SID has been shown to be a viable alternative to collision-induced dissociation (CID) ...
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 ...
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 ...
