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, ...
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 ...
Effect of plasma hardfacing and carbides presence on the occurrence of cracks and microcracks
(Institut za ispitivanje materijala, Beograd, 2018)
Presented is the effect of plasma hardfacing (or just hardfacing) and carbides presence on the occurrence of cracks and microcracks in the welded layer. The reasons behind this phenomenon are analysed and explained. In ...
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. ...
Klasifikacija opreme pod pritiskom prema direktivi 2014/68/EU i regulativi 1272/2008/EU / Classification of pressure equipment according to directive 2014/68/EU and regulation no 1272/2008/EU
(Institut za ispitivanje materijala, Beograd, 2016)
For the first time after 17 years the Directive 97/23/EC of the European Council and the Council on the harmonisation of the laws of the Member States relating to the making available on the market of pressure equipment ...
Crack initiation and propagation resistance of hsla steel welded joint constituents
(Institut za ispitivanje materijala, Beograd, 2020)
The welded joint is heterogeneous in its microstructure, mechanical and geometrical properties, thus the stress field is affected by different factors as well as by residual stress. Therefore, special procedures are needed ...
