Novel procedure to determine actual stress-strain curves
(Institut za ispitivanje materijala, Beograd, 2021)
This paper presents a novel procedure for determining the actual stress- strain curves for undermatching rectangular welded joints made of martensitic armoured steel Armox 500T. The method is based on an analytical expression ...
Modelling and Simulating the Digital Measuring Twin Based on CMM
(MDPI, Basel, Switzerland, 2023)
In order to perform the inspection planning process on the coordinate measuring machine
(CMM), it is necessary to model the measuring system with workpiece, CMM and fixture. The
metrological analysis of the workpiece is ...
Kolmogorov's Similarity Hypotheses Application in Research of the Turbulent Swirl Flows in Pipe Generated by the Various Axial Fan Geometries
(WILEY, 2021)
Kolmogorov has formulated his two hypotheses of similarity in 1941 considering local-isotropic turbulence, and later has
refined his theory [1, 2]. In this paper are discussed three turbulent swirl flows generated by the ...
Development of the Programming and Simulation System of 4-axis Robot with Hybrid Kinematic
(Belgrade : Faculty of Mechanical Engineering, 2022)
This paper presents an approach for developing the programming and offline
simulation systems for low-cost industrial robots in the
MatLab/Simulink environment. The approach is presented in the example
of a virtual model ...
WMLES of flows around small-scale propellers - estimating aerodynamic performance and wake visualization
(Srpsko društvo za mehaniku, 2023)
Wall-modeled large-eddy simulation (WMLES) is an advanced mathematical model for turbulent flows which solves for the low-pass filtered numerical solution. A subgrid-scale (SGS) model is used to account for the effects of ...
External Load Variability of Multibucket Machines for Mechanization
(Trans Tech Publications Ltd, Durnten-Zurich, 2012)
This paper discusses the problems of identifying external loads of multibucket machines for mechanization. External loads are dominantly dynamic with distinguished stochasticity in certain cases. The paper presents the ...
