Sustainable sub-geothermal heat pump heating in Serbia
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Considering the necessity of improvement of Serbian energy production structure through higher participation of clean and renewable energy sources, the possibility of utilization of low enthalpy geothermal waters have been ...
Failure analysis of the combat jet aircraft rudder shaft
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
This paper analyzes failure causes of the combat jet aircraft rudder shaft (RS) which occurred during the flight mission. A finite element method (FEM), utilized to determine the stress state of the RS subjected to hinge ...
Sensitivity Equation for Transient Three-Dimensional Heat Conduction Problem with Moving Heat Source
(Amer Inst Physics, Melville, 2010)
Sensitivity analysis of transient three-dimensional heat conduction in a plate during process of welding is performed. Crank-Nicolson method with multi-step Douglas-Gunn Alternating Direction Implicit (AD!) method is used ...
The Influence of Power and Velocity of the Heat Source on Temperature Distribution in Plate Welding Problems
(Amer Inst Physics, Melville, 2011)
The main objective of this study is to compare results obtained from some widely used simplified analytical formulas of plate welding problem to results obtained from numerical analysis of this problem based on the solution ...
Estimation of the number of trays for natural gas triethylene glycol dehydration column
(Elsevier, Amsterdam, 2011)
The paper deals with the tray-to-tray method for determining the required number of trays in columns with intensive entrainment of liquid when the operating line of the "dry working regime" is not straight and with a small ...
Measurement of local deformation fields in dental composites using 3d optical system
(Chemicke Listy, 2011)
Polymerization shrinkage is the single most important local deformation of dental composites that has a substantial effect on the quality of the tooth-restoration interface in clinical conditions. The aim of this study was ...
Influence of forward scattering on prediction of temperature and radiation fields inside the pulverized coal furnace
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
A possibility of simplification of the scattering phase function of a pulverized coal flame was analyzed in the paper. It was showed that the type of radiation scattering of a pulverized coal flame is between two limiting ...
Fracture mechanics and non-destructive testing for structural integrity assessment
(Trans Tech Publications Ltd, Durnten-Zurich, 2009)
Fracture mechanics parameters can be applied for the analysis of failures of structures, and also for prevention of failures when defects in a structure are detected and defined. The approach is presented through stages: ...
Fatigue Life Estimation of Notched Structural Components
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2010)
This work considers the analytical/numerical methods and procedures for obtaining the stress intensity factors and for predicting the fatigue crack growth life of notched structural components. Many efforts have been made ...
Surface characterisation of Pb1-XMnXTe alloy by atomic force microscopy and magnetic force mode
(MANEY PUBLISHING, LEEDS, 2011)
In this paper the authors present the results of surface characterisation of a lead telluride alloy conducted by atomic force microscopy and magnetic force microscopy. Relationship between surface morphology, in the range ...
