Practical aspects of fail-safe design - calculation of fatigue life of cracked thin-walled structures
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2011)
This paper represents fatigue crack growth life prediction in thin-walled structures (plates or shells). There are two analysis results from two different packages of software: NASGRO and FRANC 3D. They are based on Finite ...
Numerical analysis of constraint effect on ductile tearing in strength mismatched welded cct specimens using micromechanical approach
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2011)
In this paper, constraint effect on ductile fracture initiation and propagation has been studied. Three-dimensional finite element analyses of mismatched welded joints made of high strength steel, have been performed for ...
Increasing a large petrochemical company efficiency by improvement of decision making process
(Savez hemijskih inženjera, Beograd, 2010)
The paper shows the results of a research conducted in a large petrochemical company, in a state under transition, with the aim to "shed light" on the decision making process from the aspect of personal characteristics of ...
Some subtleties concerning fluid flow and turbulence modeling in 4-valve engines
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
In this paper some results concerning the structure and evolution of fluid flow pattern during induction and compression in 4- valve engines with tilted valves were presented. Results were obtained by dint of multidimensional ...
The influence of buffer layer on the properties of surface welded joint of high-carbon steel
(Institute of Metals and Technology, 2011)
Surface welding with buffer layer is often in use because of its well-known properties of plasticity, or ability to slow crack growth initiated. However, in modern surface welding technologies, buffer layer is rarely used. ...
The possibilities for measurement and characterization of diesel engine fine particles: A review
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
This review paper considers possible instrumentation for diesel engine fine particles exhaust emission evaluation. The modern diesel engines have extremely low particles emission almost at the level of measurement error ...
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 ...
Prompt system redesign: Shifting to open source technology to satisfy user requirements
(ComSIS Consortium, 2010)
The paper describes a redesign project undertaken in a short period to adapt a software system to user needs. Additional goals of the project included a shift to Open Source software and the selection of technology to ...
Numerical and experimental strength analysis of fire-tube boiler construction
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2011)
Norms, such as EN 12952-3 and EN 12953-3 handle the issues concerned with calculation of the pressurized boiler components, not however considering the influences of thermal strains that are often of vital importance for ...
An austempering study of ductile iron alloyed with copper
(Srpsko hemijsko društvo, Beograd, 2005)
Austempered ductile iron (ADI) has proved to be an excellent material as it possesses attractive properties: high strength, ductility and toughness are combined with good wear resistance and machinability. These properties ...
