Determination of Residual Fatigue Life of Welded Structures at Bucket-Wheel Excavators through the Use of Fracture Mechanics
(Elsevier Science Bv, Amsterdam, 2018)
This paper presents a methodological approach for the assessment of service life of vital welded structures of a bucket-wheel excavator Sch Rs 650/5x24 ('Thyssen Krupp', Germany) boom, subjected to cyclic loading with a ...
Mix design and engineering properties of ultra high performance self compacting concrete
(Czech Concrete Soc-Ceska Betonarska Spolecnost Cssi, Prague 1, 2011)
The mechanical properties (compressive strength and flexural strength) were investigated under different curing conditions (standard and steam curing). Silica fumes have characteristics that make them necessary in cement ...

(Trans Tech Publications Ltd, 2014)
Stable supply tank, with volume V = 250 m3 and operating pressure p = 1,5 MPa, of generation unit 6 at thermal power plant 'Nikola Tesla A' in Obrenovac, is designed for water-steam working fluid. It was made of steel Č ...
Investigation of the Repair Welding Technology Using Ni Base Electrode
(Trans Tech Publications Ltd, Durnten-Zurich, 2013)
Metal materials are subjected to innumerable time-dependent degradation mechanisms when operate in power, petrochemical and refinery plant. These materials are subjected to multiaxial stresses, creep, fatigue, corrosion ...
Properties of the Cement-Based Composites with High Content of Metakaolin
(Springer, Dordrecht, 2018)
Environmental concerns and sustainable development require increased replacement of cement. Most of previous studies have shown that the compressive strength of cement-based composites is maximized with a 20% content of ...
Low cycle fatigue of weldments produced of a high strength low alloyed steel
(Elsevier Science Bv, Amsterdam, 2014)
A quenched and tempered high strength low alloy steel NIONIKRAL 70 for producing welded pressure vessels, where high resistance to fatigue crack propagation and high tolerance of damage are of high importance, has been ...
Analysis of the cause of the girth gear tooth fracture occurrence at the bucket wheel excavator
(Elsevier, Amsterdam, 2019)
Premature damages and fractures of components and structures of bucket-wheel excavators at open-pit mine often occur in exploitation, caused either by inadequate design or insufficient knowledge of the material properties, ...
Non isothermal drying process optimisation - Drying of clay tiles
(IOP Publishing Ltd, Bristol, 2015)
In our previous studies we have developed a model for determination of the variable effective diffusivity and identification of the exact transition points between possible drying mechanisms. The next goal was to develop ...
Method for avoiding cracks during drying of masonry units made of illite raw material
(IOP Publishing Ltd, Bristol, 2019)
Drying is one of the most important steps in the production process of masonry units. In order to prevent the formation of cracks during drying information's about the moisture migration rate variability as well as the ...
Dynamics of train composition as a discrete non-homogeneous chain system
(Abstracts of 14th International conference Dynamical Systems - Theory and Applications, 2017)
The longitudinal train dynamics which included movement and oscillations of coupled railway vehicles only in the direction of the track (longitudinal) is analyzed. The one direction motion of the train, ...
