Experimental and numerical research of mechanical behaviour of titanium alloy hip implant
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
Experimental and numerical research of mechanical behaviour of hip replacement implant is presented. Experimental analysis was based on standard methods for testing mechanical properties and application of Digital Image ...
Stress Analysis of Steel Structure Comprising Cylindrical Shell with Billboard Tower
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
In accordance with EN1993-1-1, in the definition of element classes, the tubular cross section elements are considered as class 3 for cross section that respects the relation: d/t lt = 90 epsilon(2). If for any cross ...
Numerical simulation of tensile testing of pe 80 polymer specimens
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
The aim of this paper is to present the behaviour of specimens made of polyethylene material PE 80, subjected to tensile load until failure. Measurements of the temperature distribution have been done using the infrared ...
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. ...
Određivanje vrednosti unutrašnjeg pritiska koji će dovesti do plastične deformacije na modelu račve / Determination of internal pressure value causing pipe branch model to plastically deform
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2018)
Složenost geometrije posuda pod pritiskom obično predstavlja uzrok pojave koncentracije napona i deformacija. Savremeni pristup analize stanja napona i deformacija uključuje numerička i eksperimentalna ispitivanja. Svako ...
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 ...
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 ...
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 ...
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 ...
