Failure prediction of gas and oil drilling rig pipelines with axial defects
(Elsevier Science Bv, Amsterdam, 2014)
Working conditions of casing pipes in drilling rigs can significantly influence the initiation and development of damage in the material, and therefore also the safe service of the entire system. In this work, an integrity ...
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 ...
Integrity assessment of ammonia spherical storage tank
(Elsevier Science Bv, Amsterdam, 2018)
The integrity of the ammonia spherical tank (with a volume of 1800 m3 and the outer diameter of 15120 mm, nominal wall thickness 30 mm) was analyzed due to discovered cracks on the longitudinal and transverse but joints ...
The development and application of the new methodology for conveyor idlers fits testing
(Elsevier Science Bv, Amsterdam, 2018)
The proper interference fit between the joined parts is a prerequisite for an effective pressure joint. The main purpose of the pressure joint is to transfer tangential, radial and axial loads between the joined parts. In ...
Microhardness and Macrostructures of Friction Stir Welded T-joints
(Elsevier Science Bv, Amsterdam, 2018)
The results of research regarding the friction stir welding process of T-joints are presented in this paper. Experimental welding of two and three aluminium plates were performed in order to obtain T-joints. Microhardness ...
Numerical simulation of crack propagation in high-strength low-alloyed welded steel
(Elsevier Science Bv, Amsterdam, 2018)
The industrial application of high-strength low-alloyed steel (HSLA) in welded structures has increased the demand for understanding fracture behavior and structural integrity assessment of this type of steel and produced ...
Comparative Exemination of the Strengthened and Non-Strengthened NIMONIC Specimens with Laser Shot Peening Method
(Elsevier Science Bv, Amsterdam, 2018)
Laser shot peening (LSP) of material strengthening is nowdays widely used method in various branches of industry. In this paper are presented comparative exeminations of specimen made of NIMONIC and strengthened specimen ...
Finite element modeling of hip implant static loading
(Elsevier Science Bv, Amsterdam, 2016)
In this paper a numerical investigation of replacement implant for partial hip arthroplasty is presented. The long-term stability of hip implants depends, among other things, on the loads acting across the joint. Forces ...
Development of numerical-experimental model of connecting lugs and application on the lugs calculation of container terminals
(Elsevier Science Bv, Amsterdam, 2018)
The present paper describes numerical and experimental methodology and development of the model for stress and deformation state analysis of the connecting lug of container terminals. Numerical analysis was conducted by ...
Determination of Residual Fatigue Life of Welded Structures at Bucket-Wheel Excavators through the Use of Fracture Mechanics
(Elsevier Science Bv, Amsterdam, 2018)
This paper presents a methodological approach for the assessment of service life of vital welded structures of a bucket-wheel excavator Sch Rs 650/5x24 ('Thyssen Krupp', Germany) boom, subjected to cyclic loading with a ...
