Synthesis of the new Lost Foam refractory coatings based on talc
(Journal of the Serbian Chemical Society, 2022)
This paper is focused on the preparation procedures, using a talc-based filler, to improve the rheologic properties of the lost foam refractory coatings. Talc, with grain size of 40 mm, was mechanically activated in a ...
Unapređenje tehnologije aluminotermijskog zavarivanja železničkih šina različitog poprečnog preseka / Improvement of at-welding technology of railway rails with different cross sections
(Savez inženjera i tehničara Srbije, Beograd, 2021)
U radu je prikazana nova tehnologija aluminotermijskog zavarivanja (AT) prelaznih šina 49E1 na 60E1(EN 13674-1:2005.), oslonjena na potpuno nove materijale. Ona se odnosi na pešćane kalupe kod kojih su oblik i dimenzije ...
A stochastic approach for historic RC structures strengthened by ties to prevent seismic progressive collapse
(Българска академия на науките и изкуствата Научен институт по Архитектура, Строителство и Градоустройство Bulgarian academy of science and arts Scientific Institute for Architecture, Construction and Urban Planning, 2022)
Historic old existing industrial reinforced concrete (RC) structures are often subjected to removal of structural elements due to degradation caused by environmental effects. So they are in a risk of seismic progressive ...
Experimental and numerical evaluation of fracture characteristics of composite material used in the aircraft engine cover manufacturing
(Pergamon-Elsevier Science Ltd, Oxford, 2022)
The aircraft industry is a leading industry in terms of the implementation of new materials and technologies. In the development of a light aircraft several different materials were considered for the engine cover design ...
Analysis and design of the gas generator multifunctional bulkhead considering the thermal and structural loads
(Sage Publications Ltd, London, 2022)
The operation of gas generators brings relatively high thermo-mechanical loads on the gas generator structure. The objective of this article is to determine the operating conditions, in terms of mechanical loads at extremely ...
Selective laser sintered Pipe Ring Notched Tension specimens for examination of fracture properties of pipeline materials
(Engineering Fracture Mechanics, 2023)
In order to develop a non-standard method for determining the resistance to fracture and damage of pipeline materials, a new geometry of ring-shaped specimens with sharp notches or cracks has been defined. The need to ...
Printing parameter optimization of PLA material concerning geometrical accuracy and tensile properties relative to FDM process productivity
(Springer Nature, 2023)
High demand for part customization shifts industries toward AM technologies. Part customization in high-volume manufacturing is developed to its limits, whereas low-volume production using AM is still economically unjustified. ...
Tensile properties of polypropylene additively manufactured by FDM
(Society for Structural Integrity and LifeIMS Institute, 2022)
Polypropylene (PP) is an extensively studied and tested environment-friendly polymer, whose applications range from product packaging in the food industry to biomedical applications. It is a non-toxic, lightweight material, ...
Effects of Multiple Defects on Welded Joint Behaviour under the Uniaxial Tensile Loading: Fem and Experimental Approach
(MDPI, 2023)
The research represents the ongoing investigation of the welded joints behavior made
of low-carbon low-alloyed steel in the presence of different multiple defects. Following the initial
experimental and numerical analyses ...
Experimental and numerical investigation of Ti-6Al-4V alloy behaviour under different exploitation conditions
(Society for Structural Integrity and LifeIMS Institute, 2022)
The paper involves experimental testing of titanium alloy Ti-6Al-4V specimens, based on which numerical models are made to provide the basis for further investigation. Due to the exploitation conditions these implants are ...
