Numerical analysis of stress distribution in total hip replacement implant
(Institut za ispitivanje materijala, Beograd, 2017)
Total hip replacement implants represent permanent implants and require large bone and cartilage removal during implantation. Revision would affect joint capability to sustain load, which makes this procedure irreversible. ...
Effect of material heterogeneity and constraint conditions on ductile fracture resistance of welded joint zones - Micromechanical assessment
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
The topic of this work is assessment of ductile fracture initiation and development in different zones of welded joint of a high strength low alloyed (HSLA) steel. A combined experimental-numerical procedure is applied for ...
Experimental and analytical evaluation of preheating temperature during multipass repair welding
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
Experimental measurement and analytical calculation of preheating, i.e. interpass temperature during multi-pass repair welding has been presented. Analytical calculation is based on heat transfer analysis, whereas measurements ...
CFD Calculation of Helicopter Tail Rotor Airloads for Fatigue Strength Experiments
(Asce-Amer Soc Civil Engineers, Reston, 2017)
This work focuses on defining loads and fatigue life estimation of helicopter tail rotor blades. The original metal construction of these blades was replaced with a new construction of blades made from composite materials. ...
Fatigue life analysis of the integral skin-stringer panel using xfem
(Institut za ispitivanje materijala, Beograd, 2017)
Fatigue life of integral skin-stringer panels produced by laser beam welding (LBW) is analysed. This type of panel is used in airframe construction where fatigue and damage tolerance are of paramount importance, since ...
Impact of temperature and exploitation time on plane strain fracture toughness, k-ic, in a welded joint
(Institut za ispitivanje materijala, Beograd, 2017)
This paper presents the analysis of the impact of temperature and exploitation time on the tendency toward brittle fracture of welded joint constituents of new and exploited low-alloyed Cr-Mo steel A-387 Gr. B, by using ...
The economic sustainability of a model that balances ecological and power supply needs
(MM publishing Ltd., 2017)
Energy from biomass have a number of good features. These crops have a positive effect on the environment, ecology and environmental protection because they serve as a means of rebuilding the degraded area. This paper ...
Simulation of fatigue crack growth in a2024-t351 t-welded joint
(Institut za ispitivanje materijala, Beograd, 2017)
Fatigue crack growth in friction stir welded T joints under three point bending is simulated numerically using the Extended Finite Element Method (XFEM). Three point bending fatigue load stress is applied at the centre of ...
Numerical analysis of stress and strain state of structural elements of container terminal
(Institut za ispitivanje materijala, Beograd, 2017)
The results of the research regarding the stress and strain state in structural elements of the container terminal are presented in this paper. The container terminal is used for the electrical energy supply and control ...
Expectations, reality and perspectives in using bim for the green building design
(Institut za ispitivanje materijala, Beograd, 2017)
In the late 1970s when the first programs for building energy consumption simulation appeared, architectural practice was based on paper documentation and 2D drafting programs were considered as state of the art technologies. ...
