Synthesis and characterization of thermoplastic copolyester elastomers modified with fumaric moieties
(Serbian Chemical Society, 2001)
A series of poly(ether-ester)s derived from dimethyl terephthalate (DMT), dimethyl fumarate (DMF), 1,4-butandiol (BD) and poly(tetramethylene oxide) (PTMO, M̄n = 1000 g/mol) was synthesized in a two stage process involving ...
A critical review of relationships for predicting the dynamic viscosity coefficient of liquid organic compounds at saturation conditions / Kritički prikaz modela za predskazivanje koeficijenta dinamičkog viskoziteta zasićene tečnosti organskih supstanci
(Association of Chemical Engineers of Serbia, 2001)
This paper presents some empirical relationships for predicting the saturated liquid dynamic viscosity coefficient of organic compounds. Eleven models were tested using 295 experimental points for 34 organic compounds. On ...
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; ...
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 ...
