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 ...

(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2008)
This article presents part of an extensive study of the deformity mechanism of weaves, which dealing with the influence of various parameters of fabric behavior under action of different mechanical loads. Investigation of ...
Some important characteristics of woven fabrics / Neke bitne karakteristike tkanina
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2004)
In this paper characteristics of woven fabrics that might be of importance from the aspect of fabrics usage value are described. These characteristics are: thickness, area density, fabric cover, porosity, elasticity ...
Characterization of nano-powder morphology obtained by ultrasonic spray pyrolysis
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Spherical nanosized particles of copper were synthesized by ultrasonic dispersion of solutions from copper sulphate in the temperature range of 800-900°C in hydrogen atmosphere. A controlled particle size was realized ...
Investigation of antimicrobial activity of encapsulated essential oils
(8th Conference of the Yugoslav Materials Research Society, 2007)
Antimicrobial activity of essential oils obtained from many plants has been known for a long time. However, the use of essential oils as active components of biomedical textile have recently gained popularity and aroused ...
A case study on the effect of thermal residual stresses on the crack-driving force in linear-elastic bimaterials
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The effect of thermal residual stresses in bimaterial structure with initial crack located near a sharp interface is discussed in this paper. Bimaterial compact tension (CT) specimen is used in the analysis, and the residual ...
Real value of weave binding coefficient as a factor of woven fabric strength
(Inst Chemical Fibres, Lodz, 2000)
The yarn and fabric strengths of wool clothings were determined with the aim of assessing their functional dependence. Other structural parameters of investigated fabrics, such as density and yarn diameter, served for the ...
Fermentation of wheat and triticale hydrolysates: A comparative study
(Elsevier Sci Ltd, Oxford, 2009)
In bioethanol production four wheat varieties were investigated: NS 40S, Renesansa, Rapsodija and Dragana, as well as four triticale varieties: Oganj, Jutro, Odisej and NST 21/06. The samples were grinded and mixed with ...
An intensity based optical fiber sensor for low velocity impact detection in unidirectional composites
(Taylor & Francis Ltd, Abingdon, 2000)
Prevention df serious damage of composite structures might be achieved by inspecting the structural integrity during exploitation. This paper decribes the design and development of a promising optical fiber sensor system ...
Application of the residual strength degradation model to carbon-epoxy composite
(Consultants Bureau/Springer, New York, 2008)
A residual strength degradation model for two orientations of fibers of carbon-epoxy composite is proposed. The model is constructed on the basis of an analysis of a gradual decrease in the residual strength of the composite ...
