Experimental and numerical investigations of the critical values of J-integral for the steel of steam pipelines
(Elsevier Science Bv, Amsterdam, 2018)
Steel grade 14MoV6-3 is a low-carbon microalloyed steel with addition of chromium and molybdenum. This grade is designed mainly for power industry applications, withstanding operating at elevated temperatures.In this paper, ...
Determination of apparent porosity level of refractory concrete using ultrasonic pulse velocity technique and image analysis
(American Ceramic Society, 2011)
Aim of this paper is to establish the correlation between sintering process, porosity and important thermo-mechanical property of refractory concrete, i.e. creep. Creep deformation was investigated according to standard ...
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 ...
The failures of a supporting structure of a coal-reloading bridge and methodological approach to recovery of the damages
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2012)
In present paper, methodological approach to the analysis of the failures and recovery of the damages has been presented on an example of fracture and damage of a structure of the reloading bridge. The approach presented ...
Determination of the optimal drying condition during drying of green masonry products
(ModTech Publishing House, 2012)
Explanation of the drying process is reduced to the establishment of a series theoretical and empirical drying models. Complex processes of simultaneous mass and energy transfer, which are often non-stationary and the ...
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 ...
Compressive Strength Improvements of Cement-Based Composites Achieved with Additional Milling of Metakaolin
(Springer, Dordrecht, 2018)
Kaolin from a Serbian deposit, having a high content of mica and quartz, disordered kaolinite and a high specific surface area, was used to prepare metakaolin (MK). The calcination at temperatures of 700 degrees C or 750 ...
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 ...
The comparative analysis of thermal behaviour of a different thicknesses walls made from autoclaved aerated concrete blocks exposed to fire
(Proceedings of the 19th International Symposium MASE, Ohrid, 2022, 2022)
In this paper a comparative analysis of thermal behavior of six partition walls with different
thicknesses were presented. The walls were dimensions 3000 mm x 3000 mm made from autoclaved
aerated concrete blocks with ...
State Analysis and Integrity of Welded Structures of the Upper Ring of the Turbine Runner Guide Vane Apparatus of Hydroelectric Generating Set A6 on Hydro Power Plant Djerdap 1
(Trans Tech Publications Ltd, Durnten-Zurich, 2013)
During the refurbishment of the hydroelectric generating set A6 on HPP "Djerdap 1", for the state analysis and assessment of the level and causes of degradation of the structure of the vertical Kaplan turbine runner guide ...
