Strain field measurements of glass ionomer cement
(Institut za ispitivanje materijala, Beograd, 2019)
Extensive evolution of glass ionomer cements (GIC) has marked a significant shift in the practice of luting indirect dental restorations limiting the use of zinc-phosphate and zinc-polycarboxylate cements to a few indications. ...
Integrity assessment of reverse engineered ti-6al-4v eli total hip replacement implant
(Institut za ispitivanje materijala, Beograd, 2019)
Total hip replacement implants are used as an artificial replacement for disfunctional hips in order to sustain joint movement. Chosen material and design of total hip replacement are the most influential factors for ...
Repair of cracks detected in cast components of vertical kaplan turbine rotor hub
(Institut za ispitivanje materijala, Beograd, 2019)
During the revitalization of the hydroelectric generating station A4 at the hydro power plant 'Djerdap 1', all of its parts are subjected to non-destructive testing. Cracks are detected in cast part of generator rotor hub, ...
Micromechanical modelling of ductile fracture - local approach
(Savez inženjera metalurgije Srbije, Beograd, 2019)
Micromechanical modelling of ductile fracture by using the local approach has been presented as the review of previously obtained results for welded joints made of low alloyed high strength steel. Experimental work was ...
Tačka najvećeg napona na konturi kvadratnog otvora u ploči / Hot spot along corner curvature of rectangular plate opening
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2019)
Koncentracija napona u uglu kvadratnog otvora u ploči je poznata činjenica. Najčešće se uzima da je najveća koncentracija napona u samom temenu ugla (na ugaonoj koordinati od 45 stepeni u slučaju kvadratnog otvora). ...
Influence of encastering on thin-walled cantilever beams with u and z profiles on the magnitude of equivalent stress and deformation
(Institut za ispitivanje materijala, Beograd, 2019)
The purpose of this work is to present analytical and numerical determination of equivalent stress and deformation of open section thin-walled U and Z cantilever beams loaded with torsion. This work can be divided into two ...
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 from the aspect of fracture mechanics
(Institut za ispitivanje materijala, Beograd, 2019)
An increasing diversity of operations and different materials, as well as different working conditions lead to various construction solutions. Structural design is the preparation of structures that shall be efficient in ...
