Numerička analiza loma zatezne epruvete sa prslinom u ZUT / Numerical analysis of tensile specimen fracture with crack in HAZ
(Kluwer Academic Publishers, 2006)
Numeričkim rešenjima se omogućava istraživanje složenijih problema, uključujući analizu pojedinačnih uticaja, posebno u slučajevima kada izostaju odgovarajući eksperimenti i matematička rešenja usled visoke cene, složenosti ...
Simulation of Energy Absorption Effects during Helmet Collision with a Hard Obstacle
(Civil-Comp Press, 2010)
This paper presents a simulation model of the absorption effects during a helmet collision with a hard obstacle. It is based on a necessity to predict the undesirable consequences that may occur in the case of a helmet ...
Calculation of maximum tensile and shear forces in restorative materials using finite element method
(Trans Tech Publications Ltd, Durnten-Zurich, 2014)
The purpose of this paper was to determine tensile loading that leads to dental restoration failure, i.e. the critical values of stress. In order to analyze stress distribution within the restoration and tooth, mechanical ...
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 ...
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 ...
True Stress-strain Curves for HSLA Steel Weldment - Iteration Procedure Based on DIC and FEM
(Elsevier, Amsterdam, 2020)
True stress-strain curves of HSLA steel welded joint regions were estimated by using numerical simulation of strains measured by DIC and special iteration procedure to match the results. Strains were measured at certain ...
Structural dynamic modification of a tubular collector
(Proceedings of the 5th International Congress of Serbian Society of Mechanics, 2015)
Dynamic modification of structures involves the transformation of an existing model in the
new one, which has better behavior and higher accuracy in comparison with the existing. The
main objective of a dynamic modification ...
APPLICATION OF FINITE ELEMENT METHOD FOR ANALYSIS THE PARAMETERS OF FRACTURE MECHANICS
(University of Belgrade Faculty of Mechanical Engineering, Belgrade, 2022)
When making mechanical components, geometric imperfections are common, which in certain cases can cause a weak spot or some form of crack. Depending on the intensity and position of the action of forces on the mechanical ...
VIRTUAL MODEL GENERATION OF REPRESENTATIVE VOLUME ELEMENT FOR UNIDIRECTIONAL COMPOSITE
(University of Belgrade Faculty of Mechanical Engineering, Belgrade, 2022)
Composite materials are widely used in different industries because of their unique characteristics that can be adapted depending on the application. Prediction of mechanical properties before the production process enables ...
Deformation and Stress Fields in Thin Metallic Partially Fixed Plate Induced by Electromagnet with Constant Flux Obtained by Analytical Method and FEM
(The First International conference on computational mechanisc (CM’04), 2004)
In the paper the behavior of thin elastic metallic partially fixed plate produced by
electromagnet with constant flux is considered. Plate is simply supported along three edges and
fixed along the fourth one. As ...
