Lom konstrukcije strele odlagača rotornog bagera C 700 S usled dinamičkih uticaja / The structure failure of the discharge boom of bucket wheel excavator C 700 S due to dynamic effects
(Institut za ispitivanje materijala, Beograd, 2012)
Tokom operacije, kod rotornog bagera (BWE) se razvilo nepovoljno dinamičko ponašanje, plastična deformacija i lom konstrukcije. Posle sprovedene eksperimentalne/numeričke analize, potvrđeno je rezonantno dinamičko ponašanje ...
Korelacija digitalne slike u analizi eksperimentalne mehanike / Digital image correlation in experimental mechanical analysis
(Institut za ispitivanje materijala, Beograd, 2012)
Korelacija digitalne slike (DIC) je moćna beskontaktna tehnika za merenje polja pomeranja/deformacija na površinama. Neke metode, zasnivane na 2D analizi, se koriste za određivanje mehaničkih osobina epruveta jednostavnih ...
Material characterization of the main steam gate valve made of X20CrMoV 12.1 steel after long term service
(Elsevier Science Bv, Amsterdam, 2014)
Martensitic steel X20CrMo12.1 has been extensively used within the last few decades as a material for tubing systems and pipelines in thermal power plants (TPP). Long term behavior of this steel is very well known and ...
Numerical simulation of fatigue crack growth in friction stir welded T joint made of Al 2024 T351 alloy
(Elsevier Science Bv, Amsterdam, 2016)
The Extended Finite Element Method (xFEM) has been applied to simulate fatigue crack growth in an AA2024-T351 T welded joint, 5 mm thick, made by friction stir welding. The ABAQUS and Morfeo software has been used. Tensile ...
Strategija održavanja zasnovana na riziku - primenljivost na cevovod / Applicability of risk-based maintenance strategy to a penstock
(Institut za ispitivanje materijala, Beograd, 2012)
Rizik od krtog loma cevovoda reverzibilne turbine je ocenjen u ranoj fazi projektovanja. Da bi se smanjili troškovi izgradnje cevovoda prihvaćen je jedan tunel. Zbog toga je za najopterećeniji segment cevovoda izabran HSLA ...
With frequency simulation to design the monitoring of frame structures
(Institute of Physics Publishing, 2018)
Based on experience from the testing of the mining stacker in the copper mine in Bor, a practical procedure of frequency simulation of the enforced vibration of the structure was demonstrated. Modelling of the excitation ...
Numerical modelling of crack propagation in friction stir welded joint made of aluminium alloy
(Elsevier Science Bv, Amsterdam, 2014)
In this work, fatigue crack propagation in thin-walled aluminium alloy structure with two friction stir welded (FSW) joints has been numerically modelled. Crack propagation in unstiffened part of the structure between two ...
Analysis of strain distribution in overmatching V groove weld using digital image correlation
(Elsevier Science Bv, Amsterdam, 2018)
Welded joints are treated as critical sites when constructing and calculating welded structures due to inhomogeneity and anisotropy of materials at the welded joint site. Because of the change in the geometry of the elements, ...
Permanent ground displacement across earthquake faults, landslides and natural slopes
(Elsevier Science Bv, Amsterdam, 2018)
Permanent ground displacement analysis methods, as very important aspect of the seismic dynamic analysis is explained in the paper. A methodology for probabilistic hazard assessment of permanent displacement across natural ...
Multidisciplinary approach to the assessment of seismic performances and rehabilitation of bridges: nonlinear analyses, probability theory and optimization theory
(Elsevier Science Bv, Amsterdam, 2016)
The paper presents a multidisciplinary approach to the assessment of seismic performances based on the Performance-Based Earthquake Engineering (PBEE), taking into account the multi-criteria optimization theory in analyzing ...
