Identification of modular firefighting superstructures' dynamic behaviour
(Vibromechanika, 2016)
Specific functional requirements for firefighting vehicles have resulted in stricter exploitation regimes and frequent off-road use. Current practice appoints the problem of the strength of a superstructure's modules, which ...
Aerodynamic characteristics of low reynolds number airfoils
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
Assessment of airfoil aerodynamic characteristics is essential part of any optimal airfoil design procedure. This paper illustrates rapid and efficient method for determination of aerodynamic characteristics of an airfoil, ...
Numerical analysis of local and global buckling of a stiffened beam-column
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
The linear buckling phenomenon is obviously very important for stability of compressed supports. The determination of buckling resistance is an important characteristic of the design of steel structure. Besides, the presence ...
Optimization of AA5083 Friction Stir Welding Parameters Using Taguchi Method
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
In this study, Taguchi design was applied to find out the optimized set of friction steel welding parameters in terms of total crack energy, crack initiation energy, and crack propagation energy in weldments. Taguchi ...
Application of Statistical Indicators for Digital Image Analysis and Segmentation in Sorting of Agriculture Products
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
Food processing industry is moving forward to a full automation of all processes, especially in technological line segments which represent critical control points of food safety. One of these points is color sorting by ...
Stress Intensity Factors Evaluation at Tips of Multi-Site Cracks in Unstiffened 2024-T3 Aluminium Panel Using XFEM
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
The aim of this paper was to establish and demonstrate significant capacity and performances of extended finite element method (XFEM) to calculate stress intensity factors (SIFs) histories versus crack length for problems ...
Temperature and heat effects on polyethylene behaviour in the presence of imperfections
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
This paper highlights the changes of polyethylene behaviour during various loading rates as well as the influence of test temperature on the material characteristics. Passive infrared thermography method and a high speed ...
Identification of Crack Initiation Cause in Pylons Construction of the Excavator SchRs630
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
A crack occurred on gusset plate of pylon vertical truss of bucket wheel excavator (BWE) SchRs630. Numerical calculation model of pylons, slewing platform and undercarriage was formed. Calculations are done using finite ...
Superplastic deformation of an x7093 al alloy
(Institute of Metals Technology, 2014)
We have investigated the superplastic deformation mechanism of a powder-metallurgy, high-zinc X7093 Al alloy. The objective was to examine the rate-controlling mechanisms that govern its superplastic deformation. The ...
Vibration as deciding parameter during revitalization process for replacing the bucket wheel drive
(Jve Int Ltd, Kaunas, 2015)
After years of excavator`s operation in adverse conditions, one can expect a ratio between the bucket wheel drive and bucket wheel boom which may lead to impairment of structural integrity. Finite elements method is defined ...
