Influence of second-phase particles on fracture behavior of PLA and advanced PLA-X material
(Elsevier Science Bv, Amsterdam, 2021)
Most widespread materials in Additive Manufacturing are PLA (PolyLactic Acid) and ABS (Acrylonitrile Butadiene Styrene), which are dissimilar materials in terms of printing abilities and mechanical properties. PLA material ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
