Numerical and experimental strength analysis of fire-tube boiler construction
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2011)
Norms, such as EN 12952-3 and EN 12953-3 handle the issues concerned with calculation of the pressurized boiler components, not however considering the influences of thermal strains that are often of vital importance for ...
Evaluation of the local tensile properties of austenite-ferrite welded joint
(Chemicke Listy, 2011)
Local mechanical properties (Yield Strength Re and Hardening Coefficient H') of austenite-ferrite welded joint has been evaluated by using finite element method to simulate the strain distributions obtained experimentally ...
Diagnostics of bucket wheel excavator discharge boom dynamic performance and its reconstruction
(Polish Academy of Sciences Branch Lublin, 2014)
The paper focuses on an investigation into the possible causes of the bad dynamic performance of bucket wheel excavator C7OOS (BWE) discharge boom in the Kolubara opencast mine, Serbia. A discharge boom load carrying ...
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 ...
Heat input effect of friction stir welding on aluminum alloy aa 6061-t6 welded joint
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
The paper deals with the heat input and maximum temperature developed during friction stir welding with different parameters. Aluminum alloy (AA 6061-T6) has been used for experimental and numerical analysis. Experimental ...
Optical Aspect of Deformation Analysis in the Bone-Denture Complex
(Collegium Antropologicum, 2012)
The aim of this study was to register and measure any deformation of mandible models under load. The method for full field measurement of strain is done by using the ARAMIS three-dimensional image correlation system. The ...
