Analytical vs Numerical Calculation of Fatigue Life for Different Welded Joint Regions
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
This research will show the analytical way of determining the remaining life of a welded joint with a fatigue crack initiated in its heat affected zone. The calculation will be divided into two stages, since the fatigue ...
Structural Integrity Assessment of Welded Pipeline Designed with Reduced Safety
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
The main goal of this paper was to assess the integrity of welded joints in the main pipeline of the reversible hydropower plant "Bajina Bata". Japanese steel Sumiten 80P (SM 80P) was used as the parent material. European ...
Numerical-Experimental Determination of Stress and Deformation State in Connecting Lugs with the Effect of Contact Area Size
(Univ Osijek, Tech Fac, Slavonski Brod, 2019)
The present paper describes numerical and experimental methodology for the analysis of stress and deformation state in structural elements with geometrical discontinuities. The research is based on structural elements of ...
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 ...
Numerical Simulation of Fatigue Crack Growth in Titanium Alloy Orthopaedic Plates
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
Biomaterials intended for orthopaedic plates manufacturing have much higher mechanical properties relative to the bone itself and still there are many cases where those plates fracture in service, with fatigue as the main ...
Impact of the life cycle of company to job satisfaction
(Univ Osijek, Tech Fac, Slavonski Brod, 2016)
There is increased evidence indicating that employees who experience high levels of job satisfaction are also more productive. The job satisfaction is affected by Internal and external factors. The aim of this study was ...
Structural life assessment of oil rig pipes made of api j55 steel by high frequency welding
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2013)
Structural life of welded pipes made of API J55 steel by high-frequency (HF) welding has been evaluated. Experimental tests of base metal mechanical properties, including fatigue properties, were conducted on pipes after ...
Improving structure dynamic behaviour using a reanalysis procedures technique
(Univ Osijek, Tech Fac, Slavonski Brod, 2013)
The present paper deals with the problem of improving dynamic characteristics for a sub-structure of bucket wheel excavator. The procedure is concerned with the analysis of the distribution of potential and kinetic energy ...
Digital image correlation in analysis of stiffness in local zones of welded joints
(Strojarski Facultet, 2016)
The behaviour of welded joints in local zones, as well as their mutual influence, represents one of the main challenges in welded structure design. Namely, the main issue lies in determining the mechanical properties of ...
Analysis of the supporting structure of composite material tool machine using the finite element method
(Univ Osijek, Tech Fac, Slavonski Brod, 2015)
Machines aimed for different purposes must be designed taking into account specific shape, type of load and materials they are made of. Nowadays different design solutions can easily be examined by using the finite element ...
