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 ...
Production cycle time reduction in low and medium-low-tech companies: a case study for Serbia
(Univ Osijek, Tech Fac, Slavonski Brod, 2016)
Serbia is a developing country, which among other things implies underdeveloped industrial base. A fact is that more than two thirds of all Serbian industry includes low-tech and medium-low-tech companies. These companies ...
Procedure for Creating Personalized Geometrical Models of the Human Mandible and Corresponding Implants
(Univ Osijek, Tech Fac, Slavonski Brod, 2019)
The greatest challenge in engineering of human mandible implants lies in its customization for each patient individually, by adapting them to the patient's anatomical, morphological and physiological characteristics. This ...
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 ...
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 ...
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 ...
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 ...
Estimate of a power distributor life span based on the fracture mechanics criteria
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2011)
Dimensioning of pressure vessels can be done according to various criteria, the basic one being the safety against the fracture by splashing. In this paper two methods for this dimensioning procedure are presented. The ...
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 ...
