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 ...
Measurement of thermal emission during cutting of materials using abrasive water jet
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
This article deals with measurement of the thermal gradient on material during abrasive water jet cutting. The temperature was measured by thermocamera before the technological process started, during the abrasive water ...
Boundary-layer transition detection by thermography and numerical method around bionic train model in wind tunnel test
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
Methods of diagnosing aerodynamic characteristics are constantly developing in order to conduct the precise and energy efficient wind tunnel testing of transport vehicles in the prototype design early stages. This is of a ...
Influence of material velocity on heat generation during linear welding stage of friction stir welding
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
The heat generated during friction stir welding process depends on plastic deformation of the material and friction between the tool and the material. In this work, heat generation is analysed with respect to the material ...
Energy performance of single family houses in Serbia analzsis of calculation procedures
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
Energy certification of buildings in Serbia was introduced in 2011 and energy label depends on energy need for heating per unit floor area of heated space, calculated by the fully prescribed monthly quasi-steady-state ...
Diesel production by fast pyrolysis of miscanthus giganteus, well-to-pump analysis using the greet model
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
In this paper "well-to-pump" environmental analysis of pyrolytic diesel from Miscanthus gigantheus is performed. The average annual yield of Miscanthus from III-V year of cultivation on 1 ha of chernozem soil in Serbia ...
Total costs of shell and tube heat exchangers with concentric helical tube coils
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)

Creep crack growth behavior of p91 steel weldments
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
The steels operating at elevated temperatures are well known to be exposed to premature failure due to cracking caused by constant thermal stress, i. e. secondary creep process. Therefore, creep crack growth tests were ...
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 ...
