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. ...
Determining the crack acceptability in the welded joints of a wind loaded cylindrical steel shell structure
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Engineering critical 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 based ...
Fracture analysis of the pulley of a bucket wheel boom hoist system
(Polish Maintenance Soc, Lublin, 2016)
This paper presents the results of the pulley fracture analysis. Experimental investigations confirmed that the chemical composition and basic mechanical properties of the pulley material, except the impact energy at a ...
Best Practices of Biomass Energy Life Cycle Assessment and Possible Applications in Serbia
(Zagreb Univ, Fac Forestry, Zagreb, 2016)
This paper aims to highlight the advantages of using Life Cycle Assessment (or LCA) tool in energy sector for rational energy consumption, selection of green technologies and process optimization. Besides the definition ...
Determination of bond strength between the hard-faced (HF) layer and the base material (BM) of forging dies
(Faculty of Metallurgy, 2016)
This paper points out complex working conditions of forging dies, which are the most frequent causes of their damage, and proposes suitable hard-facing repair procedures. The shear strength between the hard-faced layer and ...
3D Digital Image Correlation Analysis of the Shrinkage Strain in Four Dual Cure Composite Cements
(Hindawi Ltd, London, 2019)
The introduction of resin-based cements and an adhesive-bonding system in daily dental practice has given the opportunity to increase the retention of previously conventional cemented restorations and the optimal results ...
Numerical simulation of tensile testing of pe 80 polymer specimens
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
The aim of this paper is to present the behaviour of specimens made of polyethylene material PE 80, subjected to tensile load until failure. Measurements of the temperature distribution have been done using the infrared ...
Influence of plasma spraying parameters on properties of thermal barrier coatings
(Taylor & Francis Ltd, Abingdon, 2013)
The aim of the present study is to investigate the influence of plasma spay deposition parameters on various properties of two standard thermal barrier coating (TBC) systems deposited on the steel substrate. Two TBC systems ...
