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 ...
The effect of mechano-chemical activation and surface treatment of limestone filler on the properties of construction composites
(Elsevier Sci Ltd, Oxford, 2017)
The effect of the combined actions of milling and hydrophobization procedures applied in construction composites synthesis was investigated. The mortars were prepared with cement (CEM I 42.5) and calcite aggregate complying ...

(Springer Heidelberg, Heidelberg, 2016)
The spatial distribution of major oxides (Na2O, K2O, SiO2, Al2O3, Fe2O3, CaO, MgO, MnO, TiO2, P2O5) and numerous elements (Cr, Co, Ni, Cu, Zn, As, Se, Pb, Sn, Sb, Ba, Sr, Br, Rb, Zr, Mo, Cs, Y, V, Ga, La, U, Th, Nb, W, Sc, ...
Determination of the moisture diffusivity coefficient and mathematical modeling of drying
(Elsevier Science Sa, Lausanne, 2014)
Drying plays an important role in the production of clay tiles. In the present article, drying process is analyzed taking experimental data for several masonry clays obtained from different clay tile manufacturers and ...
Mechanical properties of ultra high performance self compacting concrete with different mineral admixtures
(Revista Romana de Materiale/ Romanian Journal of Materials, 2011)
Preparation and microstructure of ultra high performance concrete (UHPC) have been intensively analyzed In the last few years. The mechanical properties (compressive strength and flexural strength) were investigated under ...
Determination of recycled aggregate concrete degradation by resonance frequency analysis
(Revista Romana de Materiale/ Romanian Journal of Materials, 2011)
The evaluation of the dynamic modulus of elasticity of twelve different concrete mix proportions as a function of the density and degradations due to freeze/thaw cycles is presented in this paper. Pore system and saturation ...
Drying simulation of shrinkable clay tiles using variable diffusivity model
(Trans Tech Publications Ltd, Stafa-Zurich, 2014)
This paper represents the upgrade of our previous study in which we have presented a model for simulation of the drying kinetic and estimation of the effective moisture diffusivity of clay tiles using a constant diffusivity ...
Failure analysis of hydraulic turbine shaft
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This paper describes the analysis of major failure of 28 MW horizontal hydro turbine shaft. The analysis of load carrying capacity of critical radius and fractography analysis are presented. Special emphasize is on ...
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 ...
