The effects of dynamic load on behaviour of welded joint a-387 gr. 11 alloyed steel
(Croatian Metallurgical Society, 2013)
The in-service behaviour of alloyed steel A-387 Gr. 11 Class 1, for pressure vessels, used for high temperature applications, depends on the properties of its welded joint, with parent metal (BM), heat-affected-zone (HAZ) ...
Microstructure and toughness of CuNiMo austempered ductile iron
(Elsevier, Amsterdam, 2004)
The effect of austempering on the microstructure and toughness of nodular cast iron (designated as CuNiMoSG) alloyed with molybdenum, copper, nickel, and manganese has been studied. Light microscopy (LM), scanning electron ...
The influence of the electric field shape on the gas breakdown under low pressure and small inter-electrode gap conditions
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 2005)
The connection between nonhomogeneities of the electric field and the value of the breakdown voltage [direct current (dc), pulls] in gases (N-2, SF6) under low pressure and small inter-electrode gap was investigated in ...
Anomalous Paschen effect
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 2005)
The aim of this paper is to discuss the area left of the Paschen minimum, i.e., the area where the anomalous Paschen effect occurs. The experimental results and numerical simulation suggest a slightly different explanation ...
The influence of ideality factor on fill factor and efficiency of solar cells
(Trans Tech Publications Ltd, 2000)
The most important output characteristics of solar cells, fill factor and efficiency strongly depend on fundamental physical properties of semiconductor materials, such as mobility. lifetime of charge carriers, diffusion ...
Aging of the over-voltage protection elements caused by over-voltages
(Pergamon-Elsevier Science Ltd, Oxford, 2002)
The aim of this work is examining the influence of the number of the activation-over-voltage pulses to the aging of over-voltage protection elements. Both non-linear (gas-filled surge arresters (GFSA), varistors, over-voltage ...
Supply water temperature regulation problems in district heating network with both direct and indirect connection
(Elsevier Science Sa, Lausanne, 1998)
General form of equations for hot water temperature in house installation and district heating system according to the outside temperature are well known. The influence of heat exchanger type and its fouling on heat output ...
Application of two independent measurement techniques for determination of ductile crack growth initiation
(Springer Netherlands, 1999)
Charpy impact testing of the high strength low-alloyed steel has been performed by simultaneously recording two independent signals. The magnetic emission (ME) and potential drop (PD) techniques were used to determine ...
Stress analysis in hydroxyapatite/poly-L-lactide composite biomaterials
(Elsevier, Amsterdam, 2001)
A three-dimensional (3D) finite element (FE) analysis of the stress concentration factor (SCF) in biocomposite model cell has been performed. The model composite consisted of a hydroxyapatite hard particle (HAp) embedded ...
Additional adjustment of the driver seat in accordance with the latest anthropometric measurements of drivers in Belgrade
(Professional Engineering Publishing Ltd, Bury St Edmunds, 2001)
This paper presents a sequel to research by two of the present authors published in 1998. In conditions of increasingly tough competition in the market, there is an increasing need to adjust automobiles to anthropomeasures. ...
