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 ...
Analysis of the flow rate and the volumetric efficiency of the trochoidal pump by application of taguchi method
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
Taguchi method has been used to analyse the influence of the coefficient of the trochoid radius, the number of revolutions and the working pressure on the change in the flow rate and the volumetric efficiency of the ...
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 ...
Testing of site-specific yield in different harvest passes
(Univ Osijek, Tech Fac, Slavonski Brod, 2016)
This paper analyzes the differences in mass yield of moist rapeseed grain for six different passes of combine harvester along the plot. The Mann-Whitney U test and Z-statistic are used for analysis needs. For harvest pass ...
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 ...
Techno-economic analysis of heat exchangers with parallel helical tube coils
(Univ Osijek, Tech Fac, Slavonski Brod, 2014)
The paper deals with the investment and exploitation costs for shell and tube heat exchangers with parallel helical tube coils. The most common correlations for estimating prices of shell and tube heat exchangers found in ...
Rigid body dynamics in optimization of the machine tool vibroisolation
(Univ Osijek, Tech Fac, Slavonski Brod, 2015)
Modern design of the machine tool treats the suspending parts as a crucial element of the effective vibration isolation. Therefore the suspending items are specifically developed and subjected to extensive tests before ...
Mechatronic approach to inventing a novel kind of deformeter
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
Stress and strain measurements on frames and structures are mainly conducted by the use of strain gauges. A measuring chain applied in such measurements usually consists of strain gauges, amplifiers and data acquisition ...
