Influence of material velocity on heat generation during linear welding stage of friction stir welding
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
The heat generated during friction stir welding process depends on plastic deformation of the material and friction between the tool and the material. In this work, heat generation is analysed with respect to the material ...
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 ...
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 ...
