Theoretical-experimental determining of cooling time (t8/5) in hard facing of steels for forging dies
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
This paper investigates the accuracy of analytical, empirical, and numerical expressions, i. e. the most favourable methods for calculating the cooling time from 800 to 500°C (t8/5). The degree of accuracy of time t8/5 is ...
Energetic analysis of hard facing and weld cladding of an air powered drop hammer damaged ram
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
This paper studies problems of hard facing of damaged and initially cracked mechanical engineering heavy parts of complex geometry such as large rams of air powered drop hammers. During long-term exploitation, these parts ...
Thermomechanical modelling the resistance welding of PbSb alloy
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
The analytical modelling of the PbSb alloy resistance spot welding process has been developed on the basis of mathematical analysis of thermomechanical conservation laws. The numerical solution of partial differential ...
Influence of temperature on behavior of the interfacial crack between the two layers
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
In this paper is considered a problem of the semi-infinite crack at the interface between the two elastic isotropic layers in conditions of the environmental temperature change. The energy release rate needed for the crack ...
