Fem model for calculation of hydro turbine shaft
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2010)
This paper describes the real problem calculation of stress state of hydro turbine shaft with crack appearance on shaft-flange radii. Finite element method (FEM) is used for calculation of shaft stress state and shaft ...
Error Bounds for Some Quadrature Rules With Maximal Trigonometric Degree of Exactness
(Amer Inst Physics, Melville, 2012)
In this paper we give error estimates for quadrature rules with maximal trigonometric degree of exactness with respect to an even weight function on (-pi, pi) for integrand analytic in certain domain of complex plane.
Recognition of Contact States in Robotized Assembly Using Qualitative Wavelet Based Features and Support Vector Machines
(Springer-Verlag London Ltd, Godalming, 2010)
This paper presents a method for recognition of contact states in robotized assembly using an example of cylindrical peg into hole part mating. Starting from force quasi-static model, offline features extraction using ...
A vortex lattice method application in aerodynamic analysis and design of light aircraft
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2010)
In initial stages of aircraft aerodynamic design, it is common practice to apply fairly simple but reliable computer packages, that enable engineers to perform a large number of test runs in a reasonably short time. This ...
Redesign of the Bucket Wheel Excavators Substructures Based on the Comparative Stress - Strain Analysis
(Trans Tech Publications Ltd, Durnten-Zurich, 2012)
Failures caused by heavy duty conditions, as well as the changes of technological requirements, are basic reasons for the redesign of specific substructures of the bucket wheel excavators (BWE). The efficient redesign ...

Digital image correlation analysis of biomaterials
(INES 2011 - 15th International Conference on Intelligent Engineering Systems, Proceedings, 2011)
Digital image correlation method (DIC) is becoming a common method in determining mechanical properties of biomaterials. DIC using 3D optical measuring system has very broad application in dentistry research field. Application ...
Quantification of stress raiser influence on decrease of machine parts fatigue life
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2012)
This paper displays the usage of Theory of Critical Distances (TCD) in the prediction of high-cycle fatigue behaviour in machine parts and systems. It is possible to gain real overview of stresses of machine parts by Finite ...
Prediction of crack initiation in spur gear contact zone
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2012)
The objective of this paper is to give a new viewpoint in contact fatigue prediction in the case of high-cycle fatigue. The presented research is based on up-to-date methods and multidisciplinary approach, and enables ...
