Numerical evaluation of thermal stresses generated in laminated composite structure exposed to low temperatures
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2021)
This paper presents numerical calculation of thermal stresses generated in a carbon fiber-epoxy laminated composite structure which is operating at low temperatures. The thermal stress evaluation is based on the finite ...
Numerical analysis of geometric characteristics of mandible fixation plates made of hydroxyapatite structures
(Institut za ispitivanje materijala, Beograd, 2019)
Bone defect reparation can be successfully performed with biomaterials based on synthetic hydroxyapatite (HA). In addition to collagen, hydroxyapatite is the basic structure of bone tissue and it is expected to have excellent ...
Application of Fracture Mechanics Parameters to Spherical Storage Tank Integrity Assessment
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
Fracture mechanics parameters have been applied to assess pressure vessel integrity. The pressure vessel analysed here was the ammonia spherical tank (volume of 1800 m(3), outer diameter 15.12 m, thickness 30 mm) where ...
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 Integrity Assessment of Welded Pipeline Designed with Reduced Safety
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
The main goal of this paper was to assess the integrity of welded joints in the main pipeline of the reversible hydropower plant "Bajina Bata". Japanese steel Sumiten 80P (SM 80P) was used as the parent material. European ...

Evaluation of the local tensile properties of austenite-ferrite welded joint
(Chemicke Listy, 2011)
Local mechanical properties (Yield Strength Re and Hardening Coefficient H') of austenite-ferrite welded joint has been evaluated by using finite element method to simulate the strain distributions obtained experimentally ...
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 ...
Numerical analysis of local and global buckling of a stiffened beam-column
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
The linear buckling phenomenon is obviously very important for stability of compressed supports. The determination of buckling resistance is an important characteristic of the design of steel structure. Besides, the presence ...
Analysis of the supporting structure of composite material tool machine using the finite element method
(Univ Osijek, Tech Fac, Slavonski Brod, 2015)
Machines aimed for different purposes must be designed taking into account specific shape, type of load and materials they are made of. Nowadays different design solutions can easily be examined by using the finite element ...
