Ispitivanje integriteta i nosivosti šipova - metodologija i klasifikacija / Pile integrity and load testing: Methodology and classification
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2019)
U radu su prikazane metodologija i klasifikacija ispitivanja integriteta i nosivosti šipova, u saglasnosti sa važećim inostranim standardima, ali i sa sopstvenim definisanim segmentima unapređivanja standarda i sopstvenim ...
Artificial fly ash based aggregates properties influence on lightweight concrete performances
(Elsevier Sci Ltd, Oxford, 2015)
The effect of the application of pelletized fly ash based aggregates obtained through different processing techniques on the behavior of lightweight concretes was analyzed. Experimental program implied production of four ...
Numerical model of fluid-structure interaction for water tower analysis of vibrations
(Institut za ispitivanje materijala, BeogradDruštvo za integritet i vek konstrukcija (DIVK), 2020)
This paper deals with the aspects of vibration analysis of 3D numerical water tower models with the explicitly generated 3D finite element (FE) solid fluid model that simulates the fluid-structure interaction (FSI). The ...
Merna nesigurnost - pojam i proceduralni koraci pri kvantifikaciji / Measurement uncertainty: Concept and procedural steps for quantification
(Srpsko društvo za puteve VIA-VITA, Beograd, 2010)
U radu je prikazan postupak analize merne nesigurnosti prilikom sprovođenja laboratorijskih merenja, što predstavlja jedan od osnovnih zahteva standarda SRPS ISO/IEC 17025 za akreditovane laboratorije za ispitivanje i ...
Application of neural networks in determination of compressive strength of concrete
(Revista Romana de Materiale/ Romanian Journal of Materials, 2012)
This paper presents the optimization of concrete mixtures composition related to a physical property and the process of production of trial mix design by using the multi-layered feed-forward neural networks. This optimization ...
Determination of the effective diffusion coefficient
(Revista Romana de Materiale/ Romanian Journal of Materials, 2011)
The equation for drying kinetics is obtained, base on the analytical solution of the differential equation with a boundary condition in the form of the flux. This equation was initially developed by G. Efremov. In this ...
Energy transfer and conversion recorded on mechanically activated fly ash grains
(ModTech Publishing House, 2015)
The fly ash activation through mechanical milling is ussualy applied to improve the ash properties in order to get composite materials with higher characteristics. The activation technology based on mechanical energy action ...
Properties of composite cement with commercial and manufactured metakaolin
(Univ Osijek, Tech Fac, Slavonski Brod, 2013)
Metakaolin composite cements were prepared with 5 to 35 % replacement of ordinary Portland cement with metakaolin (MK), manufactured by thermal activation/calcination of domestic kaolin clay, and commercial matakaolin ...
Developing Cost Estimation Models for Road Rehabilitation and Reconstruction: Case Study of Projects in Europe and Central Asia
(ASCE - American Society of Civil Engineers, 2014)
This paper presents the development of prediction models for the unit costs of road works that could be applied to strategic planning of road works at the network level. A specialized data set was used, which was generated ...
Uporedna analiza proračuna mašinskih elemenata simuliranjem kombinovanog opterećenja i odvojenim simuliranjem komponentnih opterećenja - studija slučaja / Combined load simulation vs component loads simulation in machine design: A case study
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
Na sadašnjem nivou razvoja tehnologije, u stvarnim radnim uslovima, gotovo svi mašinski elementi su opterećeni kombinovanim opterećenjima. Cilj istraživanja prikazanog u ovom radu je ukazivanje na značaj proračuna nosivosti ...
