Experimental analysis and FEM modelling of a cutting tool vibrations
(Croation Union of Mech. Engineers and Naval Architects, 2012)
Presented in this paper is a comparative analysis of vibrations, measured during machining process and modelled by FEM. Moreover, microscopic structure of chip cross section was analyzed in order to establish the frequency ...
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 ...
Experimental and numerical investigations of the critical values of J-integral for the steel of steam pipelines
(Elsevier Science Bv, Amsterdam, 2018)
Steel grade 14MoV6-3 is a low-carbon microalloyed steel with addition of chromium and molybdenum. This grade is designed mainly for power industry applications, withstanding operating at elevated temperatures.In this paper, ...
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, ...

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 ...
Effect of temperature and exploitation time on tensile properties and plain strain fracture toughness, K-Ic, in a welded joint
(Elsevier Science Bv, Amsterdam, 2018)
Effect of temperature and exploitation time on resistance to brittle fracture of welded joint constituents of new and 40 years exploited low-alloyed Cr-Mo steel A-387 Gr. B has been analysed. The plane strain fracture ...
