Numerical Simulation of Fatigue Crack Growth in Different Welded Joint Zones
(Springer Science and Business Media Deutschland GmbH, 2022)
This paper involves the numerical analysis of fatigue behaviour of welded joints made of steel SA-387 Gr. 91, with special attention devoted to its regions, which have very different mechanical and fatigue properties. ...
Loading Rate Effects on MOE and MOR Distributions in Testing of Small Clear Beech Wood Specimens
(North Carolina State Univ Dept Wood & Paper Sci, Raleigh, 2022)
Distributions of the modulus of elasticity (MOE) and modulus of rupture (MOR) were characterized at three loading rates for small clear beech specimens in static bending. The correlation between MOE and MOR for all three ...
Ion Channel Modeling beyond State of the Art: A Comparison with a System Theory-Based Model of the Shaker-Related Voltage-Gated Potassium Channel Kv1.1
(MDPI, Basel, 2022)
The mathematical modeling of ion channel kinetics is an important tool for studying the electrophysiological mechanisms of the nerves, heart, or cancer, from a single cell to an organ. Common approaches use either a ...
Contribution to the investigation of the influence of tire non-uniformity on the lateral tire characteristics
(Institut za istraživanja i projektovanja u privredi, Beograd, 2022)
Tire models are widely used in research in the field of vehicle dynamics and noise, and especially in the simulation of their movement under the action of forces and moments. In general case, we distinguish theoretical ...

Influence of the air pressure and oil amount to the temperature of the high-speed bearings lubricated by oil mist
(Emerald Group Publishing Ltd, Bingley, 2022)
Purpose The purpose of this paper is to improve the lubrication and remove as much as possible of the heat generated in the bearing assembly, embedded in the jet engine. Design/methodology/approach To determine the necessary ...
Experimental and numerical stress and strain analysis of the boiler reversing chamber tube plate
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
Boilers are one of the most used units for both heat generation plants and industry systems. Their operation is subjected to different working loads and maintenance requirements. Exploitation experience points out critical ...
Thermo-mechanical analysis of linear welding stage in friction stir welding influence of welding parameters
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
The influence of friction stir welding parameters on thermo-mechanical behav-ior of the material during welding is analyzed. An aluminum alloy is considered (Al 2024 T351), and different rotating and welding speeds are ...
Structural Integrity Analysis of a Kaplan Turbine Cover
(Elsevier Science Bv, Amsterdam, 2022)
During recent revitalization of Kaplan turbine aggregate made of structural steel St 3 (GOST standard), experimental investigation was performed. Base metal and welded joints were tested by non-destructive methods (NDT), ...
Determination of Mechanical Properties of Epoxy Composite Materials Reinforced with Silicate Nanofillers Using Digital Image Correlation (DIC)
(MDPI, Basel, 2022)
In this study, silicate nanofillers; dicalcium silicate, magnesium silicate, tricalcium silicate, and wollastonite; were synthesized using four different methods and incorporated into the epoxy resin to improve its mechanical ...
