Has the latest global financial crisis changed the way road public-private partnerships are funded? A comparison of Europe and Latin America
(Elsevier Sci Ltd, Oxford, 2020)
A financial/economic crisis may have an adverse effect on transport public-private partnerships (PPPs) as both traffic demand is negatively influenced, and governments are further under pressure. However, research on awarded ...
Assessment of Grain Size and Grain Refinement Efficiency by Calculation of Released Heat Attributed to Formation of Primary Aluminum Crystals During Solidification of Al7Si4Cu Alloy
(Springer India, New Delhi, 2021)
Assessing heat released only related to the formation of primary crystals provides results with a significantly higher sensitivity than a traditional assessment of undercooling value. In this work, two similar Ti5B1 master ...
Application of Non-Destructive Testing for Condition Analysis, Repair of Damages and Integrity Assessment of Vital Steel Structures
(Pleiades Publishing Inc, New York, 2021)
Loads at vital steel structures occur during their production and assembly (residual stresses), during the execution of functional tasks in exploitation (stationary and dynamic loads) and during the disturbed process of ...
HSLA Steel - Simulation of Fatigue
(Springer, 2020)
In present paper, based on the results of the experimental study of the behaviour of the samples made of a HSLA steel, in the form of round smooth specimens (RSS) under LCF conditions (with controlled and completely ...
Nonlinear Dynamics as a Tool in Selection of Working Conditions for Radial Ball Bearing
(Springer, 2020)
This paper contains elements of a comprehensive research devoted to the dynamic behavior of radial ball bearings in real working conditions. The general motivation for this topic comes from the requirements for high ...
Geochemical characterization of sediments from the archaeological site Vinca - Belo Brdo, Serbia
(Elsevier, Amsterdam, 2021)
In this study, a multidisciplinary approach was used for a detailed characterization of sediments from the archaeological site Vina. - Belo Brdo, Serbia, one of the most important Neolithic settlements in Europe. This ...
Application of fly ash to reduce soil dispersivity in embankments
(Publ House Bulgarian Acad Sci, Sofia, 2021)
Due to rapid development of modern highways and railroad in Serbia, the need for embankment materials has increased. Deposits of natural materials used for this purpose often contain dispersive soils. On the other hand, ...
Tie-rods of the bucket wheel excavator slewing superstructure: A study of the eye plate stress state
(Elsevier Sci Ltd, Oxford, 2020)
Tie-rods of the bucket wheel and counterweight booms are vital parts of the bucket wheel excavator slewing superstructure. This paper is dedicated to the problem of identifying the stress state of the critical cross-section ...
A Theoretical Model for Vibro-Impact Dynamics of Spur Gears with Tooth Flanks Wear
(Springer Nature, 2020)
The main performance of involute gears operation leads to the appearance of nonlinear dynamic behavior and impact. In this chapter the influence of mild wear of the tooth flanks of gears without machine finishing and surface ...
