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 ...
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 ...
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 ...
Data Driven Root Cause Analyses in Multistage Manufacturing Utilising Life Cycle Wide Product Information
(Univ Osijek, Tech Fac, Slavonski Brod, 2019)
Root cause analyses in multistage manufacturing represents inspiration for constant improvement of existing methodologies and implementation of new ones. Using quality information data from manufacturing stage and customer ...
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 ...
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 ...
Compatibility of fracture mechanics parameters and fatigue crack growth parameters in welded joint behaviour evaluation
(Strojarski Facultet, 2013)
Problem of fracture toughness, K-Ic, determination on a crack tip localized in a welded joint is set in principle, since fracture mechanics presumes homogeneous material, not only in a crack tip surrounding but on a distance ...
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 ...
