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 ...
Ekonomska opravdanost kabina kranova opremljenih računarskim sistemom vizuelnog navođenja u realnom vremenu / The economic feasibility of crane cabins with real-time computer-aided visual guidance system
(Univerzitet u Beogradu - Tehnički fakultet u Boru, Beograd, 2020)
Brojna istraživanja u oblasti nesreća u kojima učestvuju dizalice ukazuju na činjenice da je rad rukovaoca/kraniste posao visokog rizika i da je uzrok nesreća i nezgoda najčešće ljudski faktor. Shodno tome, inovacije na ...

(Institut za ispitivanje materijala, Beograd, 2021)
Development and calculation of the base supporting struc-ture used for mining equipment is the aim of the paper. The base structure is intended for the installation of electronic communication and power equipment and devices ...
Crack initiation and propagation resistance of hsla steel welded joint constituents
(Institut za ispitivanje materijala, Beograd, 2020)
The welded joint is heterogeneous in its microstructure, mechanical and geometrical properties, thus the stress field is affected by different factors as well as by residual stress. Therefore, special procedures are needed ...
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)

An overview of application of micromechanical models in ductile fracture analysis of welded joints
(Srpsko društvo za mehaniku, Beograd, 2020)
Fracture of welded joints has been an important research and industrial topic for a long time, having in mind the key role of welded joints in ensuring the safe operation and integrity of welded structures. This work ...
Load and deformation effects on brittle fracture of ferritic steel 20МnМoНi 55 in temperature transition region
(Institut za ispitivanje materijala, Beograd, 2020)
It is known that the load level, the way deformation is applied and the level of plastic strain, all can 'aid' or 'hinder' the occurrence of brittle fracture, but the question is - to what extent? These influential factors ...
Structural integrity assessment of welded bucket-wheel boom
