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 ...
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 ...
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. ...
Linear elastic and elasto-plastic aspects of interface fracture mechanics
(Institut za ispitivanje materijala, Beograd, 2020)
This paper is written on the occasion of J.R. Rice's 80th birthday. Basically, it presents two aspects of interface fracture mechanics, linear elastic and elasto-plastic, both of them reflecting the long experience of the ...
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 ...
Differences on anthropometric measurements of the hand based on laterality in Serbian context
(Institut za istraživanja i projektovanja u privredi, Beograd, 2020)
Anthropometric data are essential for designers of products, while hand anthropometric measurements are of special importance due to the fact that grasp enables different manipulation tasks. Literature review shows that ...
Impact of downtime pattern on mining machinery efficiency
(Institut za ispitivanje materijala, Beograd, 2021)
In this paper, problem of mining machinery efficiency is considered through impact of different types of downtimes. New methodology is suggested based on comparison impact of mechanical and technological mining machinery ...
