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. ...
Influence of Geometry on Pressure and Velocity Distribution in Packed-bed Methanol Steam Reforming Reactor
(Amer Inst Physics, Melville, 2017)
The main tasks of this research is to propose several changes in the packed bed micro methanol steam reformer geometry in order to ensure its performance. The reformer is an integral part of the existing indirect internal ...
The new experimental testing methodology for conveyor idler's fits control
(International Conference on Fracture, 2017)
The most common way to transfer tangential and axial loads in different types of assemblies is by interference fits. It is essential to determine interference fit parameters of pressed joints, which provides a proper ...
Structural integrity of a wind loaded cylindrical steel shell structure
(Elsevier Science Bv, Amsterdam, 2017)
The structural integrity and life assessment can be considered as a mandatory request in the civil engineering designing and manufacturing process. The paper is presenting the procedure for determination of crack acceptability ...
Temperature and time effects on fatigue strength of weldments
(International Conference on Fracture, 2017)
Temperature and service time effects on A-387 Gr. B Cr-Mo steel weldment fatigue strength have been evaluated. To assess service time effect on fatigue strength, samples are take from 40 years “old” material, whereas ...
Aplication of Metal Matrix Composite Coatings in Thermal Power Plants
(4th Conference of the Serbian Society for Ceramic Materials, Programme and the book of abstracts, 2017)
Nanomaterials for sustainable energy production and storage: Present day applications and possible developments
(Springer International Publishing, 2017)
Currently used technologies in energy industry are oftentimes potentially harmful for the environment and/or not sustainable in the long run (e.g. fossil and mineral based fuels, nuclear energy). Therefore the oncoming ...
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. ...
