Probability distribution on cleavage fracture in function of Jc for reactor ferritic steel in transition temperature region
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
This paper presents the results and methods used for determining of probability of cleavage fracture toughness of ferritic reactor steel in transition temperature area. The steel tested in this study is steel know as ...
Determination of the Actual Stress-Strain Diagram for Undermatching Welded Joint Using DIC and FEM
(MDPI, Basel, 2021)
This paper presents new methodology for determining the actual stress-strain diagram based on analytical equations, in combination with numerical and experimental data. The first step was to use the 3D digital image ...
Model of seismic design lateral force levels for the existing reinforced concrete European building stock
(Springer, Dordrecht, 2021)
As part of the development of a European Seismic Risk Model 2020 (ESRM20), the spatial and temporal evolution of seismic design across Europe has been studied in order to better classify reinforced concrete buildings (which ...
Dose effect of gamma radiation on reliable voltage pulse measurement in nuclear fusion experiments
(Taylor & Francis Ltd, Abingdon, 2021)
The effect of gamma radiation on the reliable measurement of single voltage pulses of electron beam injectors into plasma during fusion experiments is considered in the manuscript. For this purpose, a 10 GHz fast voltage ...
Differences in Serbian and Libyan crane operators' anthropometric measurements and cabin interior space modeling
(IOS Press, Amsterdam, 2021)
BACKGROUND: Previous research has shown that the collection and analysis of crane operators' anthropometric characteristics is very important for operators' comfort, health and working ability and also from the aspect of ...
Failure analysis and numerical simulation of slab carrying clamps
(Gruppo Italiano Frattura, Cassino, 2021)
The goal of this study was to determine the reasons for failure of slab carrying clamps which had occurred in one of the clamp support levers. Detailed fractography analysis revealed that there was a welded joint at the ...

(Institut za ispitivanje materijala, Beograd, 2021)
The paper presents a solution applied for determining the quality of the welding process in oil and gas industrial plants, as well as reliable verification of professional qualification of welding personnel. By applying ...
New insights into physics of explosive water boiling derived from molecular dynamics simulations
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
In this paper the dynamics of explosive boiling of a 72 angstrom thick water film on the hot copper substrate with the plain surface is analysed. The analyses are based on the results of molecular dynamics (MD) simulations ...
Impact of downtime pattern on mining machinery efficiency
(Institut za ispitivanje materijala, Beograd, 2021)
In this paper, problem of mining machinery efficiency is considered through impact of different types of downtimes. New methodology is suggested based on comparison impact of mechanical and technological mining machinery ...
Structural integrity analysis of a cracked pressure vessel
(Institut za ispitivanje materijala, Beograd, 2021)
Stress distribution, as obtained by finite element method (FEM), and corresponding fracture mechanics parameters, have been used for the integrity assessment of a pressure vessel. Once the stress distribution is known, the ...
