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 ...
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 ...
Numerical analysis of the response of the rc flat slab building under seismic action
(fib. The International Federation for Structural Concrete, 2021)
Investigation of the behaviour of flat slab system has been intensified in the last years. Wide use of flat slab systems due to the fast construction and simplicity of formwork has as the results presence of flat slab ...
Algorithm for defining quality of base material for repair welding
(Institut za ispitivanje materijala, Beograd, 2021)
The paper shows the comparison of different methodologies for defining the quality of base material due for repair welding as one of the basic and initial problems during the repair of damaged parts or machine equipment. ...
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 ...
Povećanje energetske efikasnosti parnog bloka iskorišćenjem otpadne toplote dimnog gasa
(Beograd : Savez mašinskih i elektrotehničkih inženjera Srbije (SMEITS), 2021)
U termoelektranama sa starijim projektnim rešenjima postoji značajan potencijal za iskorišćenje otpadne toplote
dimnih gasova. Otpadna toplota dimnog gasa se može iskoristiti primenom zagrejača vode visokog pritiska ...
Increased hydraulic resistance in tubes of once-through boiler due to fouling: a case study of 650 MWe ligite fired unit
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), 2022)
The analysis of pressure changes in water and steam flow along the entire once-through steam
boiler tube system at the 650 MWe lignite fired Unit was carried out after the long operational period
of almost 30 years ...
Numerical simulation of crack growth in a welded joint with defects
(Elsevier B.V., 2021)
Research presented in this paper involves the numerical simulation of crack growth in a welded joint made of common structural steel S235JR2, but with the presence of a number of different welding defects, which represents ...
