Failure investigation and reparation of a crack on the boom of the bucket wheel excavator ERS 1250 Gacko
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Bucket wheel excavator ERs 1250 has been in operation for over 30 years in the Grae'anica-Gacko mining basin. It is operating in very hard working conditions due to exploiting very solid material, which has adverse effects ...
Effect of aging on mechanical properties of Al-8Si-8Fe-1.4v/SiCp composites
(Faculty of Metallurgy, 2016)
In this study, Al-8Fe-8Si-1.4V/SiCp composites fabricated by squeeze casting process were age-hardened to Study the influence of heat treatment on mechanical properties, such as hardness, bending strength and modulus of ...
Experimental determination of brittle fracturing appearance during static indentation of materials based on stone
(Springer Heidelberg, 2017)
During micro cutting process, the presence of both ductile and brittle mode is observed. The appearance of one or the other, or the value of critical penetration depth, when transition is happening, depends on the material ...
Characterizing the Mechanical Properties of Fused Deposition Modelling Natural Fiber Recycled Polypropylene Composites
(MDPI, Basel, 2017)
The objective of this investigation was to characterize the performance of natural fiber reinforced polypropylene composites in fused deposition modelling (FDM). Composite filaments comprising of pre-consumer recycled ...
Production cycle time reduction in low and medium-low-tech companies: a case study for Serbia
(Univ Osijek, Tech Fac, Slavonski Brod, 2016)
Serbia is a developing country, which among other things implies underdeveloped industrial base. A fact is that more than two thirds of all Serbian industry includes low-tech and medium-low-tech companies. These companies ...

Fracture mechanics and fatigue crack propagation in armor steel welds
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The welding process of armor steel is a complex process due to possible welding faults appearing in all zones of weld metal joint in the form of cracks and pores, as results of high percentage of carbon in the base metal. ...
Modelling of creep behaviour of a rotating disc in the presence of load and variable thickness by using seth transition theory
(Institut za ispitivanje materijala, Beograd, 2018)
The purpose of this paper is to present study of creep behaviour of a rotating disc in the presence of load and thickness by using Seth's transition theory. It has been observed that a flat rotating disc made of compressible ...
