Physical and metallurgic changes during the friction welding of high-speed cutting steel and tempered steel
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2009)
This paper outlines the basic principles of welding by friction of high-speed cutting steel and tempered steel from the viewpoint of metallurgic processes that are going on in the material. The bases of welding by friction ...
Unapređenje održavanja dijagnostikovanjem stanja i ponašanja rotornih bagera on-line i off-line metodom / Improvement of bucket wheel excavator maintenance by on-line and off-line method of condition and behavior diagnostics
(Savez inženjera i tehničara Srbije, Beograd, 2009)
Dijagnostika stanja i ponašanja je od presudnog značaja za donošenje pravilnog stava o radu i održavanju rotornog bagera, odnosno svih komponenti bagera, od čelične konstrukcije pa do pogonskih grupa. Da bi jedan rotorni ...
Radiation Absorption Characteristics of Titanium Alloys
(Polish Acad Sciences Inst Physics, Warsaw, 2009)
Titanium alloys have found numerous applications in space research, and nuclear industry and research. Since X-rays constitute an important part of the space radiation environment, numerical simulations of radiation ...
Development and application of crack parameters
(Springer, Dordrecht, 2009)
The development, definition and implementation of crack parameters (stress intensity factor, crack tip open displacement, J integral, filial stretch zone) are presented. They are now used for structural integrity and ...
Variable Coefficients Model for Drying Processes with Conductive Heat Supply
(Taylor & Francis Inc, Philadelphia, 2009)
The proposed model is for heat and mass transfer inside a layer of moist material placed on hot isothermal surface. The relevant thermophysical properties of the material are considered as fully dependent on local temperature ...
Analiza prigušenja konstrukcije tipa ljuske od legure titana u poređenju sa konstrukcijom od legure aluminijuma / Analysis of structural damping of titanium alloy shell structures as compared with that of aluminium alloy structures
(Institut za ispitivanje materijala, Beograd, 2009)
U ovom radu se razmatra mehaničko ponašanje konstrukcije od legure titana sa aspekta određivanja osnovnih dinamičkih karakteristika. Analiziran je numerički model za konstrukcije legure titana tipa ljuske (osnovni konačni ...
Analysis of loading steel structure of bucket wheel excavator by stress condition measuring
(Institute of Mechanical Engineering, 2009)
Fracture mechanics and non-destructive testing for structural integrity assessment
(Trans Tech Publications Ltd, Durnten-Zurich, 2009)
Fracture mechanics parameters can be applied for the analysis of failures of structures, and also for prevention of failures when defects in a structure are detected and defined. The approach is presented through stages: ...
Analiza otpornosti ka lomu ZUT-a u zavarenim spojevima mikrolegiranih čelika povećane čvrstoće / Analysis of the HAZ fracture resistance of HSLA steel weldments
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2009)
Ispitivane su karakteristike otpornosti ka lomu u ZUT zavarenog spoja mikrolegiranog čelika povećane čvrstoće koji se koristi za izradu posuda pod pritiskom. S obzirom na namenu zavareni spoj treba da ima veliku otpornost ...
