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 ...
Stress Analysis of Steel Structure Comprising Cylindrical Shell with Billboard Tower
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
In accordance with EN1993-1-1, in the definition of element classes, the tubular cross section elements are considered as class 3 for cross section that respects the relation: d/t lt = 90 epsilon(2). If for any cross ...
Novel Risk Based Assessment of Pressure Vessels Integrity
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
New methodology for risk based approach to integrity assessment of pressure vessels has been introduced. Namely, the risk matrix has been defined with consequence taken as usual, whereas probability has been separated into ...
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 ...
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 ...
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. ...
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 ...
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 ...
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 ...
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 ...
