Analytical solution of elastic-plastic stresses in thin rotating disc made up of piezoelectric material
(Institut za ispitivanje materijala, Beograd, 2020)
This paper presents an analytic solution of transitional and plastic stresses in a thin rotating disc made up of piezoelectric material under internal pressure. The stresses in the rotating disc are calculated by applying ...
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 of bicycle frame composite structure based on stacking variant of laminate layers
(Institut za ispitivanje materijala, Beograd, 2020)
No matter what kind of bike the parts belong to (according to the requirements they need to meet), these parts are almost identical. The most complex bicycle part in the structural optimization for manufacture is a bicycle ...
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 ...
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 ...
The effect of heat input on the fracture behaviour of surface weld metal of rail steel
(Institut za ispitivanje materijala, Beograd, 2020)
Surface welding of rail steel with self-shielded wire was conducted with different heat inputs, and the influence of welding heat input on the total impact energy and its components, crack growth rate and fracture mechanism ...
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 ...
Structural integrity and life assessment of oil drilling rig pipes using analytical method
(Institut za ispitivanje materijala, Beograd, 2022)
Structural integrity and life assessment of oil rig pipes using analytical method is presented and applied to an oil drilling rig pipe. The new concept based on risk evaluation according to probability and consequence of ...
TENSILE TESTING OF FLAT THIN SPECIMENS USING THE TWO-DIMENSIONAL DIGITAL IMAGE CORRELATION METHOD
(Structural Integrity and Life, 2023)
Conventional tensile testing is most commonly used for determining the basic mechanical properties of the material. However, this approach is challenging for in-depth analysis of material behaviour, especially related to ...
Experimental Mechanical Characterization of Parts Manufactured by SLA and DLP Technologies
(Structural Integrity and Life, 2023)
Since the beginnings of additive manufacturing (AM) in the 1980s, vat polymerization was the first and most intensively developing technology that enabled the production of very precise parts from photosensitive polymer ...
