Dinamičke metode za ispitivanje šipova / Dynamic methods for pile testing
(Savez građevinskih inženjera Srbije, Beograd, 2013)
U radu su opisane četiri metode za ispitivanje šipova. Dve metode, "Sonic integrity testing" (SIT) i "Crosshole ultrasonic method" (CHUM) orijentisane su ka ispitivanju integriteta šipova, a dve metode "Dynamic load testing" ...
Analysis of the nominal load effects on gear load capacity using the finite-element method
(Sage Publications Ltd, London, 2010)
This research investigates the effects of the nominal load value on load distribution of simultaneously meshing gear teeth pairs, and on the involute gear load capacity. The research results presented in this article confirm ...
A Theoretical Model for Vibro-Impact Dynamics of Spur Gears with Tooth Flanks Wear
(Springer Nature, 2020)
The main performance of involute gears operation leads to the appearance of nonlinear dynamic behavior and impact. In this chapter the influence of mild wear of the tooth flanks of gears without machine finishing and surface ...
Assessment of the effect of pitting corrosion on fatigue crack initiation in hydro turbine shaft
(Trans Tech Publications Ltd, 2013)
Energy efficiency is a key issue worldwide, and not confined solely to the realm of engineers. Past failures of mechanical power system components must be examined carefully in order to minimise future occurrences and ...
48 Years of Fracture Mechanics and Structural Integrity in South East Europe
(Springer-Verlag Berlin, Berlin, 2017)
Development of fracture mechanics and structural integrity in South East Europe has been presented and analysed. As the starting point, the Magister thesis of Prof. Stojan Sedmak, 48 years ago (1968), has been taken, ...
Thermal and Mechanical Behavior of Composite Mortars Containing Natural Sorptive Clays and Fly Ash
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
Mineral additives are extensively applied as cement replacement materials in both construction concrete and mortar. Fly ash is one of the most commonly utilized additives which improve Theological properties, as well as ...
What is the most relevant method for water absorption determination in ceramic tiles produced by illitic-kaolinitic clays? The mystery behind the gresification diagram
(Sociedad Espanola de Ceramica y Vidrio, 2020)
This study presents the 51 mixtures of ceramic clays characterized by using XRF, XRD, granulometry, and dilatometry analyses. After firing in a 1000-1250 °C range, water absorption (WA) according to EN standards by boiling ...
Fired pressed pellet as a sample preparation technique of choice for an energy dispersive X-ray fluorescence analysis of raw clays
(Elsevier, 2022)
In this paper, the main subject concerns comparing different techniques to prepare raw clay samples for energy dispersive X-ray fluorescence spectrometry (EDXRF). Three kinds of sample preparation procedures are examined,such ...
Life Assessment of Corroded Wire for Prestressing
(MDPI, 2023)
The repair of structural elements for the prestressing of reinforced concrete is necessary
when existing prestressing wires are damaged or after a certain period of time. The objective of this
paper is to describe the ...
Structure and properties of ZnO/ZnMn2O4 composite obtained by thermal decomposition of terephthalate precursor
