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 ...
Numerical analysis of different weld geometries of lap welded joint in ammonia transport tanks
(Institut za ispitivanje materijala, Beograd, 2017)
Presented is a comparison of stress and strain distribution in lap welded joints of different geometries, which are part of a pressure vessel used as an ammonia transport tank. For this purpose, two numerical models are ...
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 ...
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 ...
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 ...
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 stress distribution in total hip replacement implant
(Institut za ispitivanje materijala, Beograd, 2017)
Total hip replacement implants represent permanent implants and require large bone and cartilage removal during implantation. Revision would affect joint capability to sustain load, which makes this procedure irreversible. ...
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 ...
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 ...
