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 ...
Energetic analysis of hard facing and weld cladding of an air powered drop hammer damaged ram
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
This paper studies problems of hard facing of damaged and initially cracked mechanical engineering heavy parts of complex geometry such as large rams of air powered drop hammers. During long-term exploitation, these parts ...
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 ...
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 ...
