Stress Analysis of Steel Structure Comprising Cylindrical Shell with Billboard Tower
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
In accordance with EN1993-1-1, in the definition of element classes, the tubular cross section elements are considered as class 3 for cross section that respects the relation: d/t lt = 90 epsilon(2). If for any cross ...
Numerical simulation of tensile testing of pe 80 polymer specimens
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
The aim of this paper is to present the behaviour of specimens made of polyethylene material PE 80, subjected to tensile load until failure. Measurements of the temperature distribution have been done using the infrared ...
Numerical modelling and experimental validation of elastic - plastic behaviour of pressure vessel with nozzles
(Innovation Center of Faculty of Mechanical Engineering, Belgrade, 2017)
To evaluate the safety of welded structures, such as pressure vessels, it is necessary to know the material properties of which vessels are made and their behavior under different working conditions. Due to various ...
HYDROXYAPATITE STRUCTURES AND NUMERICAL ANALYSIS OF THE GEOMETRIC CHARACTERISTICS OF THE LOWER JAW FIXATION PLATES
(Central Institute for Conservation, BelgradeScientific Association for the Development and Promotion of New Technologies, 2017)
Bone defect reparation can be successfully performed with biomaterials based on synthetic hydroxyapatite (HAP). In addition to collagen, hydroxyapatite is the basic structure of bone tissue and it was expected to have ...
Numerical and experimental determination of stress concentration factor for a pipe branch model
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
The subject of this paper is testing of complex geometrical structures, i.e. stress analysis of a pipe branch model of A6 third pipeline at Hydropower Plant Perucica, Niksic. Analysis of pipe branch model stress distribution ...
Modeling of the metal cylinder acceleration under explosive loading
(Belgrade : Military Technical Institute, 2013)
The paper considers the motion of a cylindrical metal liner caused by expanding products of internal detonation. A new analytical model of cylinder motion is developed for the case of axial initiation of an explosive charge. ...
Structural dynamic modification of a tubular collector
(Proceedings of the 5th International Congress of Serbian Society of Mechanics, 2015)
Dynamic modification of structures involves the transformation of an existing model in the
new one, which has better behavior and higher accuracy in comparison with the existing. The
main objective of a dynamic modification ...
Temperature fields and residual stresses in welded joints of high-strength steel / Temperaturska polja i zaostali naponi u zavarenim spojevima čelika povišene čvrstoće
(Univerzitet u Beogradu, Mašinski fakultet, 2014)
The effect of the residual stresses and strains is one of the most important parameters in the structural integrity assessment. A finite element model is constructed in order to simulate the multi passes mismatched submerged ...
Analysis of the stress field in a model of pipe branches
(Proceedings of TEAM 2015, 7th International Scientific and Expert Conference of the International TEAM Society, 2015)
The aim of this paper is to analyze the stress field of
a complex geometry model of pipe branches loaded
with internal pressure of 10 bar. The analysis will be
done by comparing method of strain gauges and a
new one ...
Determination of internal pressure value causing pipe branch model to plastically deform
(International Conference of Experimental and Numerical Investigations and New Technologies, 2017)
Complexity of pressure vessels geometry usually causes stress and strain concentrations. Modern approach of stress and strain analysis involves numerical and experimental testing. Every experimental testing on the construction ...
