Welding safety by using a new model of welders' recertification in the oil and gas industry
(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 ...
Numerical simulation of welded joint with multiple various defects
(Institut za ispitivanje materijala, Beograd, 2021)
The paper presents continuation of extensive work on determining the behaviour of welded joints in the presence of multiple various types of defects, a problem that is not sufficiently covered by existing standards, such ...
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 ...

Explosive boiling of water films based on molecular dynamics simulations: Effects of film thickness and substrate temperature
(Elsevier, 2023)
This paper deals with investigations of mechanisms governing explosive boiling of water films on hot copper substrate with plain surface. The investigations are based on results of molecular dynamics (MD) simulations in ...
Composite material selection for aircraft structures based on experimental and numerical evaluation of mechanical properties
(Elsevier Science Bv, Amsterdam, 2021)
In this paper determination of mechanical properties of composite material using experimental and numerical approach is presented. The mechanical properties of a laminate obtained in the experiment are used for verification ...
Numerical simulation of fatigue crack growth in AA6156 T6 panels
(Elsevier B.V., 2021)
Fatigue crack growth in a panel with 4 stringers and 3-clips, made of AA6156 T6, was modelled numerically using xFEM. The central crack of the length a=17 mm was propagated in the total of 91 steps (in each step crack ...
Experimental and numerical methods for concept design and flow transition prediction on the example of the bionic high-speed train
(Springer, 2021)
In the times of significant development of high-speed train transportation and taking the primacy over the others, one of the major designing tasks is to predict accurately and fast the vehicle’s main performances, especially ...
Thermalhydraulics of once-through steam boiler tubes revisited
(Department of Thermal Technology, Gliwice, Poland, Silesian University of Technology 2020, 2020)
The analysis of pressure changes in water and steam flow along the entire once-through steam boiler
tube system was carried out. An efficient advanced method is developed and presented for the
prediction of once-through ...
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 ...
