The effect of cracks on stress state in crane wheel hard-surface under contact loading
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
Shown in this paper are the results of microstructure testing of crane wheels, along with the repair welding procedure performed by hard-surfacing. Repair welding involved the application of a welded layer to the crane ...
The Reliability of Bucket Wheel Excavator - Review of Random Mechanical Failures
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
Statistical regularity of random mechanical failures of the bucket wheel excavator will be considered based on dispatcher's reports about excavator-conveyors-spreader (ECS-III) on the Tamnava - West Field Open Cast Mine ...
Risk Model for Integrated Management System
(Univ Osijek, Tech Fac, Slavonski Brod, 2019)
The purpose of this paper is to develop an integrated risk management model for standardized management systems: ISO 9001:2015 for quality management, ISO 14001:2015 for environmental management, ISO/IEC 27001:2013 for ...
Application of Fracture Mechanics Parameters to Spherical Storage Tank Integrity Assessment
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
Fracture mechanics parameters have been applied to assess pressure vessel integrity. The pressure vessel analysed here was the ammonia spherical tank (volume of 1800 m(3), outer diameter 15.12 m, thickness 30 mm) where ...
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 ...
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 ...
Physical and metallurgic changes during the friction welding of high-speed cutting steel and tempered steel
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2009)
This paper outlines the basic principles of welding by friction of high-speed cutting steel and tempered steel from the viewpoint of metallurgic processes that are going on in the material. The bases of welding by friction ...
Damage tolerance analysis of structural components under general load spectrum
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2012)
In this investigation fatigue behaviour of damaged structural components under cyclic loads constant amplitude and load spectrum is considered. Primary attention of this investigation is the establishment of computation ...
Measurement of strain using stereometry
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2009)
This paper presents measurement of strain using stereometry method. It describes the use of digital stereometry to measure microstrains on the surface. This can be achieved by comparison of the images of point distribution ...
