Bucket chain excavator: Failure analysis and redesign of the counterweight boom supporting truss columns
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The supporting truss of the counterweight boom is a vital part of the bucket chain excavator's (BCE) superstructure. The occurrence and propagation of cracks in the supporting truss columns' heads may lead to BCE collapse. ...
Pregled eksplicitnih aproksimacija Kolbrukove jednačine za koeficijent trenja / A review of explicit approximations of Colebrook's equation
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2011)
U radu je dat pregled najčešće korišćenih eksplicitnih jednačina za određivanje koeficijenta trenja u glatkim i hrapavim cevima. Odstupanje navedenih jednačina od Kolbrukove jednačine izraženo je preko srednje relativne ...
Determination of braking force of aerodynamic brakes for high speed trains
(Transactions of Famena, 2011)
This paper presents the results of simulations, carried out with the Fluent software, for a high speed train moving at 70 m/s for 4 cases: the train configuration without aerodynamic brakes, the train configuration with ...

Prompt system redesign: Shifting to open source technology to satisfy user requirements
(ComSIS Consortium, 2010)
The paper describes a redesign project undertaken in a short period to adapt a software system to user needs. Additional goals of the project included a shift to Open Source software and the selection of technology to ...
Poređenje modela razmene toplote zračenjem koji se koriste za numeričke simulacije kotlovskih ložišta / Comparison of radiative heat transfer models used in numerical simulations of boiler furnaces
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd i Društvo termičara Srbije, Beograd, 2010)
Toplotno zračenje je dominantni mod prostiranja toplote sa vrućih produkata sagorevanja ka zidovima ložišta. Tačnost računanja flukseva zračenja je od suštinskog značaja za tačnost numeričkih simulacija, kojima se mogu ...
Procena integriteta konstrukcije implanta veštačkog kuka izrađenog od višefazne Co-Cr legure / Structural integrity assessment of hip implant made of cobalt-chromium multiphase alloy
(Institut za ispitivanje materijala, Beograd, 2010)
Rad prikazuje analizu parametara mehanike loma višefazne Co-Cr legure, koja se koristi kao materijal za implant kod ugradnje veštačkog kuka. Konstrukcijski parametri koje bi trebalo uzeti u obzir tokom projektovanja implanta ...
The Geometry Influence on Integrity Thresholds for a Cracked Cylinder
(wiley, 2010)
By applying the EPRI engineering approach, threshold values of pressure for internally pressurized axially cracked long cylinder are calculated. The JR curve and the crack driving force J are approximated by polynomials ...
Improvement of algorithm for numerical crack modelling
(Springernature, London, 2010)
For numerical simulation of crack modelling in fracture mechanics the eXtended finite element method (Xfem) has been recently accepted as a new powerful and efficiency methodology. In the paper we present the details of ...
