Using the image analysis program for prediction of thermal stability behavior of refractory specimen
(8th International Symposium on Multifunctional and Functionally Graded Materials, FGM2004, 2005)
Most important properties which are usually measured for refractories are work temperature and thermal stability. Thermal stability of the alumina based samples was measured using a standard laboratory procedure, the water ...
Chain conformational statistics and mechanical properties of elastomer composites
(Progress in Advanced Materials and Processes: Proceedings of the Fifth Jugoslav Materials Research Society, YUCOMAT V, 2004)
A new equation of state for elastomer network under constrains due to fillers has been proposed and verified for two most common and industry important rubbers, natural rubber and styrene-butadiene rubber. A series of ...
Conduction mechanism based model of organic field effect transistor structure
(8th Conference of the Yugoslav Materials Research Society, 2007)
Carriers mobility model of olygomer and polymer semiconductor based OFET (Organic Field Effect Transistor) structures is presented in this paper. Starting from the conduction mechanism in the mentioned organic materials, ...
The activity of iron-containing zeolitic materials for the catalytic oxidation in aqueous solutions
(8th Conference of the Yugoslav Materials Research Society, 2007)
In this work, a series of iron-containing zeolitic materials has been tested as heterogeneous catalysts for decomposition of H2O2 and for oxidation of the cationic dye Methylene Blue with H2O2 in aqueous solutions. FeAPO ...
Fracton scaling and dynamical properties of elastomer materials
(8th Conference of the Yugoslav Materials Research Society, 2007)
Scaling of the real and the imaginary part of dynamic moduli with frequency, for fully cured elastomer materials as gum and active carbon black filled butyl rubbers, is considered experimentally and theoretically. For gum ...
Damage analysis of particulate polymer composites based structure by using micro-meso-macro finite element approach
(12th International Manufacturing Conference in China, IMCC2006, 2006)
A micro-meso-macro finite element approach has been developed for simulating the macro-scale damage coupled deformation in a particulate polymer composite (PPC) based structure under tension. A damage model for the PPC ...
Finite element modeling of mechanical properties of particulate composite biomaterials
(Proceedings of the fourth Yugoslav Materials Research Society Conference (YUCOMAT IV), 2002)
The influence of inclusion geometry and volume fraction on stiffness behavior of a particle hydroxyapatite filled polymer (poly-L-lactide and collagen) matrix composite was investigated by finite element. analysis. The ...
Hydrogels based on 2-hydroxyethyl methacrylate obtained by gamma irradiation
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Hydrogels based on 2-hydroxyethyl methacrylate and different types of poly(alkylene glycol) acrylates and methacrylates, with a small percent of itaconic acid, have been prepared by solution copolymerization using gamma ...
Theoretical assessment of calcium arsenates stability: Application in the treatment of arsenic contaminated waste
(8th Conference of the Yugoslav Materials Research Society, 2007)
Several approaches for immobilization of arsenic (As) based on the transformation of its soluble forms (compounds) into highly insoluble arsenate apatite Ca5(AsO4)3 OH have been proposed. These immobilization techniques ...
Low energy impact damage detection in laminar termoplastic composite materials by means of embedded optical fibers
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The possibility of applying optical fibers as sensors for investigation of real time low energy impact damage in laminar thermoplastic composite materials has been studied. For that purpose intensity based optical fibers ...
