An Analysis of Continuous Sandwich Panels with Profiled Faces
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2017)
Structural sandwich panels made of two thin steel facings that are bonded to a thick mineral wool core are often used as roofing material. This paper explores an application of numerical simulations in the investigation ...
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 ...
Uporedna analiza metoda proračuna uticaja lokalnog savijanja pojasa jednošinskih nosača dizalica / Calculation methods' comparative analysis of monorail hoist crane local bending effects
(Savez inženjera i tehničara Srbije, Beograd, 2016)
Rezultati numeričko-eksperimentalnih istraživanja problema lokalnog savijanja, obavljenih na klasičnim i srednje širokim I profilima, predstavljali su osnovu za donošenje aktuelnog standarda (EN 15011:2014) koji propisuje ...
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 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. ...
Procena integriteta čeličnih konstrukcija pomoću uporedne modalne analize / Integrity assessment by cross correlated modal identification of steel structures
(Univerzitet u Beogradu, Mašinski fakultet, 2015)
Dosadašnja istraţivanja u obasti integriteta čeličnih konstrukcija bazirana su uglavnom na analitičkim procenama veka strukture kroz numeričke proračune i ispitivanja konvencionalnim eksperimentima. Numeričke metode, ma ...
