Micromechanical analysis of constraint effect on fracture initiation in strength mismatched welded
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
In this paper the micromechanical approach to ductile fracture was applied in a study of constraint effect on crack growth initiation in mismatched welded joints. The single-edged notched bend specimens (precrack length ...
Sintering of Cu-Al2O3 nano-composite powders produced by a thermochemical route / Sinterovanje nano-kompozitnih prahova Cu-Al2O3 dobijenih termohemijskih postupkom
(Serbian Chemical Society, Belgrade, 2007)
This paper presents the synthesis of nano-composite Cu-Al2O3 powder by a thermochemical method and sintering, with a comparative analysis of the mechanical and electrical properties of the obtained solid samples. ...
Experimental and numerical evaluation of a steamline behaviour using local approach
(Croatian Metallurgical Society, 2007)
Results of the experimental and numerical comparative analysis of steamline pipes have been presented. New pipes and the pipes used for more than 117,000 hours at 540 degrees C under pressure of 42 bars have been simultaneously ...
Optimization of processing parameters for preparation of LaNiO3 thin films from the citrate precursors
(Elsevier Sci Ltd, Oxford, 2007)
Lanthanum nickel oxide (LaNiO3) is an electrically conductive ceramics, which has a potential use as electrode for ferroelectric thin films, multilayer actuators and many other electronic devices. In this work, LaNiO3 thin ...
Properties of aliphatic hyperbranched polyesters in dilute solutions
(Serbian Chemical Society, 2007)
The results of an investigation of the influence of the synthesis procedure, number of pseudo generations and degree of branching of hydroxy-functional aliphatic hyperbranched polyesters (AHBP) on the values of limiting ...
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 ...
Solvent and structural effects on the kinetics of the reactions of 2-substituted cyclohex-1-enylcarboxylic and 2-substituted benzoic acids with diazodiphenyl with diazodiphenylmethane
(Wiley, Hoboken, 2007)
The rate constants for the reaction of 2-methyl-cyclohex-1-enylcarboxylic, 2-phenylcyclohex-1-enylcarboxylic, and 2-methylbenzoic and 2-phenylbenzoic acids with diazodiphenyl-methane were determined in 14 various solvents ...
Removal of methyl tertiary butyl ether from wastewaters using photolytic, photocatalytic and microbiological degradation processes
(Elsevier Science Bv, Amsterdam, 2007)
Contamination of groundwater by methyl tertiary butyl ether (MTBE), that is detected in wastewater of petrochemical industry, is an increasing problem to water supply companies. The subjects of this research were the methods ...
Crack tip strain on ship and in situ measurement in shipyards
(IFAC Proceedings Volumes (IFAC-PapersOnline), 2007)
The paper presents the application extent of procedures for measurement deformations on ships. The actual deformation distribution was measured on the surface of the specimen by the optical grating method (OGM) parallel ...
Numerical and analytical modeling of elastic-plastic fracture mechanics parameters
(8th Conference of the Yugoslav Materials Research Society, 2007)
Structural integrity and service reliability depend on the fracture resistance of a material. Cracks in the material are the locations of stress concentration, and elastic-plastic deformation can occur causing the development ...
