Experimental and numerical analysis of thermo-chemical erosion in gun steel
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
Various factors of thermo-chemical erosion process in gun steel were analysed. The factors are mainly related to the thermal load of gun barrel inside surface, characteristics of barrel surface and chemical interactions ...
Temperature fields in linear stage of friction stir welding effect of different material properties
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
Friction stir welding is one of the procedures for joining the parts in solid state. Thermo-mechanical simulation of the friction stir welding of high-strength aluminium alloys 2024 T3 and 2024 T351 is considered in this ...
Air staging application effects on overall steam boiler operation
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
This paper presents the results of calculation system of main processes in power steam boiler, before and after application of air staging. Modified air injection scheme was implemented during 2015 on the power steam boiler ...
Modeling of the buckstay system of membrane walls in watertube boiler construction
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Membrane walls are very important structural parts of water-tube boiler construction. Based on their specific geometry, one special type of finite element was defined to help model the global boiler construction. That is ...
Numerical aspects for efficient welding computational mechanics
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The effect of the residual stresses and strains is one of the most important parameter in the structure integrity assessment. A finite element model is constructed in order to simulate the multi passes mismatched submerged ...
Thermal manifestations and nanoindentation of bone cements for orthopaedic surgery
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Improving of bone cements properties is possible by research of variables influencing exothermal behaviour and mechanical properties. Paper deals with exothermal behaviour experimental evaluation of bone cements used for ...
Finite element modelling of creep process - steady state stresses and strains
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Finite element modelling of steady state creep process has been described. Using an analogy of visco-plastic problem with a described procedure, the finite element method has been used to calculate steady state stresses ...
Influence of friction stir welding parameters on properties of 2024 t3 aluminium alloy joints
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The aim of this work is to analyse the process of friction stir welding (FSW) of 3 mm thick aluminium plates made of high strength aluminium alloy - 2024 T3, as well as to assess the mechanical properties of the produced ...
Thermomechanics of soft inelastics bodies with application to asphalt behavior
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Thermomechanical behavior of hot mix asphalt (HMA) is considered. Its highly irregular microstructure is covered by the hierarchical approach. A brief survey of endochronic thermodynamics precedes constitutive consideration. ...
Numerical analysis of temperature field during hardfacing process and comparison with experimental results
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The three-dimensional transient nonlinear thermal analysis of the hard facing process is performed by using the finite element method. The simulations were executed on the open source Salome platform using the open source ...
