Analysis of SA 387 Gr. 91 welded joints crack resistance under static and impact load
(Elsevier Science Bv, Amsterdam, 2021)
This paper presents the results of experimental testing of crack resistance of specimens taken from a welded plate made of steel SA-387 Gr. 91, while taking into account different filler materials and welding procedures ...
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 ...
Structural integrity assessment of welded bucket-wheel boom
(Institut za ispitivanje materijala, Beograd, 2021)
Research is conducted on the causes of damage and the structural integrity assessment of the bucket-wheel boom welded lattice structures, before and after the repair of vital structures. Additionally, the paper describes ...
Repair welding procedure and techno-economic analysis of burner pipe
(Institut za ispitivanje materijala, Beograd, 2021)
The selection of the electrode for repair welding is one of the activities needed before repairing machine parts. In this case, damages that have occurred in a burner pipe welded joint during manufacture or previous repair ...
Finite element analysis of spherical storage tank stress state
(Institut za ispitivanje materijala, Beograd, 2021)
In this paper, a spherical storage tank for the storage of liquefied petroleum gas is analysed. A design calculation of structural elements is performed according to valid standards and technical regulations. Seismic loads ...
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. ...
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 ...
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 ...
