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 ...
Influence of material velocity on heat generation during linear welding stage of friction stir welding
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
The heat generated during friction stir welding process depends on plastic deformation of the material and friction between the tool and the material. In this work, heat generation is analysed with respect to the material ...
Experimental and numerical study of globe valve housing
(Savez hemijskih inženjera, Beograd, 2017)
Complex structure experimental analysis has always been a huge challenge for researchers. Conventional experimental methods (e.g., strain gauges) give only limited data sets regarding measurement on critical areas with ...
Combined Measuring Uncertainty of Capacitive Divider With Concentrated Capacitance on High-Voltage Scale
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 2018)
This paper is aimed at expressing the expanded combined measuring uncertainty of capacitive divider with concentrated capacitance on a high-voltage scale. The tested capacitive divider is constructed to have a minimal ...
Simulation of Flat Die Deep Drawing Process by Variable Contact Pressure Sliding Model
(Univ Osijek, Tech Fac, Slavonski Brod, 2019)
Influence of the contact pressure in the deep drawing processes is a very actual research topic in the metal forming technology. Within this research the tribological model of the strip sliding in the flat die was developed. ...
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 ...
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 ...
Experimental and numerical research of mechanical behaviour of titanium alloy hip implant
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
Experimental and numerical research of mechanical behaviour of hip replacement implant is presented. Experimental analysis was based on standard methods for testing mechanical properties and application of Digital Image ...
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 ...
Experimental-Numerical Study of Tensile Strength of the High-Strength Steel S690QL at Elevated Temperatures
(Springer, New York, 2016)
We present the experimental-numerical analysis of the influence of temperature on mechanical properties of structural high-strength steel class S690QL. Since the steel S690QL belongs to a group of steels with good mechanical ...
