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 ...
Heat and mass transfer during contact drying of a sheet of moist material
(Thermal Science, 1999)
Observed are the processes of heat and mass transfer inside the layer (sheet) of wet material placed on flat heating surface of constant, but variable and controllable temperature, and exposed, from above, to the horizontal ...
The characteristics of combustion process of diesel engine using vegetable oil methyl esters
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2015)
Biodiesel is one of the promising renewable, alternative, and environmentally friendly biofuels that can be used in Diesel engine with little or no modification in the engine. The present paper investigates the combustion ...
Numerical and experimental determination of stress concentration factor for a pipe branch model
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
The subject of this paper is testing of complex geometrical structures, i.e. stress analysis of a pipe branch model of A6 third pipeline at Hydropower Plant Perucica, Niksic. Analysis of pipe branch model stress distribution ...
Influence of secondary phases in A356 MMCs on their mechanical properties at macro- and nanoscale
(Springer Heidelberg, Heidelberg, 2020)
Metal matrix composites are very inhomogeneous materials, and their properties depend on various parameters (production process, constituents, their interfaces, etc.). The influence of SiC microparticles (40 mu m) reinforcement ...
Thermal history and stress state of a fresh steam-pipeline influencing its remaining service life
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
The service life of thick-walled power plant components exposed to creep, as is the case with pipelines of fresh- and reheated steam, depend on the exhaustion rate of the material. Plant operation at elevated temperatures ...
An Approach to the Optimization of a Thin-walled Z-beam
(Strojniski Vestnik/Journal of Mechanical Engineering, 2009)
One approach to the optimization of a thin-walled open section Z-beam subjected to bending and to the constrained torsion is considered. For given loads, material and geometrical characteristics the problem is reduced to ...
MKE model zupčanika sa kosim zupcima za analizu naponskog stanja i nelinearnu analizu kontakta / Finite element model for stress analysis and nonlinear contact analysis of helical gears
(Vojnotehnički institut, Beograd, 2009)
Određivanje naponskog i deformacionog stanja na bokovima i u podnožju zubaca jedan je od osnovnih zadataka u toku proračuna opterećenja i provere nosivosti zupčanika. U ovom radu opisan je postupak razvijanja modela konačnih ...
Spregnuti nelinearni problemi u analizi konačnim elementima - studija slučaja / Coupled nonlinear problems in finite element analysis: A case study
(Integritet i vek konstrukcija, Beograd, 2012)
Rad daje opis analize elastoplastičnih deformacija čeličnog cevnog apsorbera kinetičke energije sudara železničkih vozila metodom konačnih elemenata (FEM). Eksperimentalna istraživanja korišćena su kao osnova za modeliranje ...
High-temperature deformation behaviour of Ti3Al-11Nb intermetallic
(Carl Hanser Verlag, Munich, 2011)
A mechanism of high-temperature plasticity has been studied in terms of stress exponent and activation energy for deformation. A Ti3Al-based intermetallic was processed by hot-rolling in the two-phase field to accomplish ...
