Numerical simulation of fatigue crack propagation: A case study of defected steam pipeline
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In order to prevent the premature failure of steam pipeline produced of molybdenum-vanadium steel, the experimental tests were performed to measure fracture toughness and to determine the mechanical behaviour of cracked ...
Experimental study on the stresses at the i-beam end-plate moment connection
(Institut za ispitivanje materijala, Beograd, 2019)
The paper deals with experimental study of the stresses at the bolted end-plate moment connection. The design parameters are adopted to include prying effects in joint. A stress level is obtained in the elements where the ...
Water retention parameters and sediment dispersivity of the Zemun loess plateau (Belgrade, Serbia)
(Publ House Bulgarian Acad Sci, Sofia, 2019)
The paper presents the results of recent investigations of the Zemun Loess Plateau, which focused on unsaturated and dispersive loess soil. Soil water retention curves, SWRCs, were determined experimentally, using a pressure ...
Assessment of the effectiveness of producing mineral fillers via pulverization for ceramic coating materials
(Wiley, 2019)
The effectiveness of employment of mechano-chemical activation in the production of high temperature ceramic coating materials was assessed. The properties of mineral fillers are directly dependant on the choice of activation ...
Effects of mechanical-activation and TiO2 addition on the behavior of two-step sintered steatite ceramics
(Elsevier Sci Ltd, Oxford, 2019)
Steatite, as ceramic with composition predominantly resting on magnesium silicate, was produced from economic resources - talc, aluminosilicate clays, and either BaCO3 or feldspar as flux. Titanium dioxide was a doping ...
Effect of LCF on behavior and microstructure of microalloyed HSLA steel and its simulated CGHAZ
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Numerous structural components made of high strength low-alloyed steels are often exposed to low-cycle fatigue loading during their exploitation life. In order to study the fatigue behavior of one grade of structural steels ...
Ispitivanje integriteta i nosivosti šipova - metodologija i klasifikacija / Pile integrity and load testing: Methodology and classification
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2019)
U radu su prikazane metodologija i klasifikacija ispitivanja integriteta i nosivosti šipova, u saglasnosti sa važećim inostranim standardima, ali i sa sopstvenim definisanim segmentima unapređivanja standarda i sopstvenim ...
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, ...
Physical-Mechanical Properties of Cement Stabilized RAP/Crushed Stone Aggregate Mixtures
(Univ Osijek, Tech Fac, Slavonski Brod, 2019)
The paper presents and analyzes the results of testing the properties of cement stabilized mixtures of reclaimed asphalt pavement (RAP) and crushed stone aggregate (CSA). Tests were carried out on reclaimed asphalt pavement ...
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 ...
