Numerical determination and experimental validation of the fracture toughness of welded joints
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Most of the serious weldment failures lead to catastrophic consequences in terms of damage of other equipment, loss of production, and risks to workers' health and safety. Hence, there is motivation to find margin between ...
J-integral Analysis of the Simulated Heat-affected Zone of the Elevated-temperature Martensitic Steel
(Springer, New York, 2021)
Due to its superior strength at high temperatures P/T91 steel is often applied in the chemical, petrochemical and fossil-fired power generation industries. The high strength is achieved by a suitable martensitic microstructure ...
Assessment of Efficiency of Rare Earth Elements Recovery from Lignite Coal Combustion Ash via Five-Stage Extraction
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2021)
Rare earth elements (REE) are frequently referred to as ingredients for enhancements in modem industry, as they are extensively applied in many industrial branches due to their accented electro-magnetic and optical properties. ...
Experimental and Discrete Element Model Investigation of Limestone Aggregate Blending Process in Vertical Static and/or Conveyor Mixer for Application in the Concrete Mixture
(MDPI, Basel, 2021)
The numerical model of the granular flow within an aggregate mixture, conducted in the vertical static and/or the conveyor blender, was explored using the discrete element method (DEM) approach. The blending quality of ...
An Artificial Neural Network-based Prediction Model for Utilization of Coal Ash in Production of Fired Clay Bricks: A review
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2021)
This study analyzed the last 20 years' data available on power plant coal ashes used in clay brick production. The statistical analysis has been carried out for a total of 302 cases based on the relevant parameters reported ...
Performances of Vermiculite and Perlite Based Thermal Insulation Lightweight Concretes
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2020)
This experimental study was conducted with an aim to investigate the effect of the elevated temperature on the mineral phase composition, microstructure and mechanical properties of the thermal insulation lightweight ...
Optimization of adobe clay bricks based on the raw material properties (mathematical analysis)
(Elsevier Sci Ltd, Oxford, 2020)
This research studies the effects of composition and granulometry analysis of 139 heavy clays on the important characteristics of wet and adobe clay bricks. ANN models were obtained with high prediction accuracy in training ...
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 ...
Model of Probabilistic Analysis of Pile Capacity Based on the Extrapolation of Load-Settlement Curves
(Springer, New York, 2020)
This paper formulates a mathematical model using the extrapolation of load-settlement curves with a rational function for analyzing the capacity of piles obtained from the static load test (SLT). In preliminary analyses, ...
