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 ...
External atmospheric influences on the mechanical properties of resin-bonded grinding wheels with aluminium oxide and silicon carbide grains
(Institut za ispitivanje materijala, Beograd, 2020)
Ageing effects on resin-bonded grinding wheel properties are presented, including aluminium oxide and silicon carbide influence. Furthermore, humidity is examined as the most likely cause of significant downgrade in ...

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 ...
