Integrity assessment of turbine flat cover pipe
(Institut za ispitivanje materijala, Beograd, 2018)
The turbine flat cover pipe (dimension phi 219.1x12.7 mm, and material STPG-38) is tested and cracks are found. Determination of the required wall thickness for a pipe exposed to internal pressure is done according to EN ...
Non-homogeneity effect in the spherical shell by using seth's theory
(Institut za ispitivanje materijala, Beograd, 2017)
This paper presents nonlinear deformation behaviour of non-homogeneous spherical shell examined under pressure by using Seth's transition theory. It has been seen that for increased material compressibility in thickness ...

Determination of Residual Fatigue Life of Welded Structures at Bucket-Wheel Excavators through the Use of Fracture Mechanics
(Elsevier Science Bv, Amsterdam, 2018)
This paper presents a methodological approach for the assessment of service life of vital welded structures of a bucket-wheel excavator Sch Rs 650/5x24 ('Thyssen Krupp', Germany) boom, subjected to cyclic loading with a ...
Numerical analysis of heat transfer during friction stir welding
(Institut za ispitivanje materijala, Beograd, 2017)
The paper deals with the heat input and maximum temperature that develops in friction stir welding with different welding parameters. The finite element method has been used for numerical analysis of temperature distribution ...
Experimental and numerical cross-correlated modal analysis of the floor structure dynamics in a thermal power plant
(Institut za ispitivanje materijala, Beograd, 2015)
This article presents search methodology after the cause of excessive floor vibrations in a thermal power plant control room. The floor structure is a composition of a steel grillage and concrete slabs at 12 m level above ...
Pregled literature iz oblasti skladišnih sistema baziranih na šatl tehnologiji / A survey of literature on shuttle based storage and retrieval systems
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2018)
Prethodna decenija donela je pravi procvat u oblasti automatskih skladišnih sistema (SBS/RS) baziranih na šatl tehnologiji u mnogim industrijama. Njihova superiornost u odnosu na 'mini-load' automatske skladišne sisteme ...
Analysis of fracture behaviour of thin s316l stainless steel plates
