Optimization of AA5083 Friction Stir Welding Parameters Using Taguchi Method
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
In this study, Taguchi design was applied to find out the optimized set of friction steel welding parameters in terms of total crack energy, crack initiation energy, and crack propagation energy in weldments. Taguchi ...
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 ...
Analysis of Comfort Parameters in Special Purpose Vehicles from Technological Development Point of View
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
The analysis of comfort parameters in the crew cabin space of two variants of the special purpose off-road vehicle is presented, taking technological development aspects into account. Tests of noise, vibration and heating ...
Experimental and Numerical Analysis of Fatigue Crack Growth in Integral Skin-Stringer Panels
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
Experimental and numerical analysis of fatigue crack growth in integral skin-stringer panels, produced by means of laser beam welding (LBW), is performed. Since this type of panel is used in airframe construction, fatigue ...
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 ...
Evaluation of the Locking Compression Plates Stress-Strain Fields
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
Locking Compression Plates (LCP) have found application in the orthopaedic healing process in modern medicine. Their design is specifically modified depending on the bone and the loading the specific bone is subjected to. ...
Fatigue Life Estimation of Damaged Integral Wing Spar Using XFEM
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
This paper presents the application of the extended finite element method (XFEM) in crack propagation simulation on the integral wing spar that should replace existing differential spar of the light aircraft UTVA 75. ...
Possibility of Reducing the Overpressure of Shock Wave of Powder Gases around the Mortar
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
This paper resulted from the research of the overpressure of the shock wave of the powder gases, which occurs during firing of the mortar. Work encompasses modeling and computation of the overpressure field. Increasing ...
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 ...
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 ...
