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 ...
A scaling approach to size effect modeling of J(c) CDF for 20MnMoNi55 reactor steel in transition temperature region
(Pergamon-Elsevier Science Ltd, Oxford, 2022)
Ever since the 1980s there is a sustained interest in the size effect, as one of the most pronounced consequences of fracture mechanics. In the present study, the investigation of the size effect is focused on estimation ...
The Effect of Material Heterogeneity and Temperature on Impact Toughness and Fracture Resistance of SA-387 Gr. 91 Welded Joints
(MDPI, Basel, 2022)
This paper presents the analysis of the behavior of welded joints made of 9-12% Cr-Mo steel SA-387 Gr. 91. The successful application of this steel depends not only on the base metal's (BM) properties but even more on ...
The effects of welded clips on fatigue crack growth in AA6156 T6 panels
(Elsevier Ltd, 2022)
Fatigue crack growth in different panels, made of AA6156 T6, was investigated experimentally and numerically. Three different types of panels were used, simple one, so-called base metal (BM), panel with 4 welded stringers ...
Fatigue crack growth in locking compression plates
(Elsevier Sci Ltd, Oxford, 2022)
Fatigue crack growth in orthopaedic locking compression plates (LCP), under four-point bending, has been simulated by the extended finite element method (xFEM) to assess LCP optimal geometry in respect to remaining life. ...
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 ...
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 ...
Effect of material heterogeneity and testing temperature on fatigue behaviour of Cr-Mo steel welded joints
(Elsevier Ltd, 2022)
Successful application of Cr-Mo steel depends crucially on behaviour of all zones in welded joints, i.e. base metal (BM), heat-affected-zone (HAZ) and weld metal (WM), both at room and working temperature. Different amplitude ...
